MANOVA is used to compare multivariate sample means across more than two dependent variables, commonly applied in education and psychology research. However, some papers incorrectly use MANOVA for univariate research questions rather than multivariate questions. Additionally, some MANOVA assumptions like linearity of dependent variables and homogeneity of covariance matrices can be difficult to satisfy. More modern alternatives like linear mixed effects models and multiple imputation may be superior for analyzing repeated measurements or missing data. The document discusses challenges with MANOVA and potential alternative statistical methods that are better suited for certain research questions and designs.

NTLTC 2011 - student use of academic resources in assignments
This document summarizes research conducted by a psychology lecturer and librarian on the sources used by students in an introductory psychology course. They analyzed the reference pages from 124 student assignments to categorize source types and calculate descriptive statistics. They found that on average students used 3-4 sources, most frequently the provided textbook and journal articles as well as an instructor summary. Library sources were rarely used. Statistical testing suggested effects of online vs print submission and a relationship between number of sources used and mark achieved. Future analysis of additional assignments is planned.

This document provides an introduction to regression analysis and statistical methods. It discusses that regression analysis estimates the linear relationship between dependent and independent variables. Multiple linear regression allows studying the relationship between one dependent variable and two or more independent variables. The accuracy of regression models can be evaluated using measures like R-squared and testing overall model significance. Diagnostic tests of assumptions like independence of errors, normality, homoscedasticity and absence of multicollinearity/influential outliers are important.

This document presents a study that developed predictive models to identify at-risk students in a first-year engineering course based on learning objective performance data. The study tested six predictive modeling methods and an ensemble method on student data from two semesters. The naive Bayes classifier and ensemble method were most successful at prediction. Feature selection revealed the midterm exam and performance in week 5 had the strongest relationship to student success. The models can help instructors identify struggling students and gain insights to improve pedagogy.

This document discusses parametric and nonparametric statistical tests. Parametric tests like the t-test and ANOVA assume a normal distribution of data and compare population means. Nonparametric tests do not assume a normal distribution and can be used when sample sizes are small or distributions are unknown. Specific parametric tests covered include the t-test for comparing two groups, one-way ANOVA for comparing three or more groups on one factor, and two-way ANOVA for examining two factors. Examples of how and when to use these various tests are provided.Quantitative Data Analysis: Hypothesis Testing

Stereotype Modeling for Problem-Solving Performance Predictions in MOOCs and ...
This study examined whether student stereotypes could be used to improve predictions of problem-solving performance in MOOCs. The researchers tested simple stereotypes based on demographics and performance, but found they did not yield accurate models of different student groups' learning. More advanced stereotypes based on patterns of problem-solving behavior also did not distinguish groups with significantly different learning models. The findings suggest stereotypes may not effectively represent the finer-grained differences in how students approach learning. Overall, the study did not find evidence that stereotype models can improve predictions of problem-solving over alternative models of individual student learning.
research category using the MANCOVA.pptx
MANCOVA is used to analyze data with more than one dependent variable and one or more independent variables while controlling for covariates. It extends MANOVA and ANCOVA by incorporating multiple dependent variables and a covariate. A one-way MANCOVA determines if there are statistically significant differences between adjusted group means of an independent variable on combined dependent variables after controlling for a continuous covariate. Key requirements include more than one dependent variable measured on a ratio scale, an independent variable with two or more groups, a covariate with two or more groups, and meeting assumptions like homogeneity of variance and normality. The procedure involves stating hypotheses with the null that the independent variable is not a factor and the alternative that it is, analyzing data

Repeated anova measures ppt
Repeated measures ANOVA is used to compare average scores on the same individuals across multiple time periods or treatment conditions. It controls for individual differences by having each subject serve as their own control. The repeated measures ANOVA tests whether population means are equal across conditions while accounting for within-subject variability. It has advantages of increased power but disadvantages like carryover effects. Assumptions include continuous, normally distributed dependent variables and independence of observations.
Week 6 DQ1. What is your research questionIs there a differen.docx
Week 6 DQ
1. What is your research question?
Is there a difference between the math utility of a male and a female?
2. What is the null hypothesis for your question?
Hn There is no difference in the math utility between male and female.
Alternative hypotheses can also be created in the case the null hypothesis is proven incorrect. Two alternative hypotheses are:
Ha1 Feales have a higher math utility.
Ha2 Males have a higher math utility.
3. What research design would align with this question?
According to Frankfort-Nachmias and Leon-Guerrero (2015) a descriptive research design would be best for this type of study.
4. What comparison of means test was used to answer the question (be sure to defend the use of the test using the article you found in your search)?
The independent-samples T test was used to analyze the means for this data.
5. What dependent variable was used and how is it measured?
The dependent variable is the student’s math utility. It is measured from -3.51 to 1.31(University high school longitudinal study dataset. (2009).
6. What independent variable is used and how is it measured?
Either male (1) of female (2) (University high school longitudinal study dataset. (2009).
7. If you found significance, what is the strength of the effect?
The significance was 0.0000. This is much better than the standard of .05 significance as outlined by Frankfort-Nachmias and Leon-Guerrero (2015).
8. Identify your research question and explain your results for a lay audience, what is the answer to your research question?
My research question was “Is there a difference between the math utility of a male and a female?” Based on the analysis of the means (or average) through testing using the independent-samples T test there was no measurable difference between the math utility of male or females. This leads us to accept the null hypothesis of “There is no difference in the math utility between male and female” as true.

Urothelial cancer causes 200,000 global deaths annually with only a 5% 5-year survival rate. The document compares cancer immunotherapy (ICI) to chemotherapy and other treatments using overall survival and progression-free survival metrics from clinical trials. Machine learning models including gradient boosting machines, generalized linear models, and random forests are developed and validated on IMvigor210 and IMvigor211 datasets to predict survival outcomes and enhance efficiency and accuracy over traditional clinical models. The first study to use machine learning to predict responses to ICI in urothelial cancer is presented, with the models accurately stratifying risk but limitations in promoting the new approach industrially.

The first study to use machine learning to predict responses to ICI in urothelial cancer is presented, with the models accurately stratifying risk but limitations in promoting the new approach industrially.
Factor analysis in R with Five Personality Survey Mini Sample
This document discusses conducting a factor analysis on survey data measuring the Big Five personality traits. It summarizes the key steps in a factor analysis including data preparation, checking assumptions, model fitting, interpretation and further analysis. Specifically, it extracts the extraversion questions from the survey, checks the data meets assumptions, runs a factor analysis with weighted least squares extraction and no rotation to identify one factor related to extraversion questions. It proposes next steps like analyzing the other personality traits and combining with other techniques like PCA and cluster analysis.
Logistic regression
This document does not contain any meaningful information to summarize. It consists entirely of symbols and formatting characters without any words, sentences, or discernible meaning. A proper summary cannot be generated from this input.
Trade war Bayesian Analysis
This document analyzes the potential effects of new tariff policies between the US and China using Bayesian analysis and trade data from 2002-2016. It identifies the most valuable trading categories between the two countries and summarizes tariff goods trade. The analysis finds that tariff goods make up 4% of total global trade, and China and US together account for 25% of that 4% tariff goods trade. Therefore, the new tariff policies are estimated to impact around 1% of total global trade.
Data Analysis on Crime Rate
The document summarizes a study analyzing the correlations between community crime rates and various risk factors in the United States. It describes cleaning a dataset of over 2215 communities, then performing exploratory data analysis including correlation tests and principal component analysis. Linear regression models were developed to predict violent and non-violent crime rates based on factors like income, ethnicity, family structure, and housing. The violent crime model achieved an R-squared of 0.59, accurately predicting crime rates based on the selected variables.
Anly 500-presentation
This document presents a study analyzing the relationship between social media data and box office performance of movies. It finds Twitter conversation volume is highly correlated with box office numbers. The study uses linear regression models to predict opening weekend box office based on Twitter volume and theater counts. A model using only total Twitter volume can explain 68% of box office variance, while adding theater counts improves accuracy. The models show social data can successfully predict box office performance far in advance of a film's release.

Global Situational Awareness of A.I. and where its headed
You can see the future first in San Francisco.
Over the past year, the talk of the town has shifted from $10 billion compute clusters to $100 billion clusters to trillion-dollar clusters. Every six months another zero is added to the boardroom plans. Behind the scenes, there’s a fierce scramble to secure every power contract still available for the rest of the decade, every voltage transformer that can possibly be procured. American big business is gearing up to pour trillions of dollars into a long-unseen mobilization of American industrial might. By the end of the decade, American electricity production will have grown tens of percent; from the shale fields of Pennsylvania to the solar farms of Nevada, hundreds of millions of GPUs will hum.
The AGI race has begun. We are building machines that can think and reason. By 2025/26, these machines will outpace college graduates. By the end of the decade, they will be smarter than you or I; we will have superintelligence, in the true sense of the word. Along the way, national security forces not seen in half a century will be un-leashed, and before long, The Project will be on. If we’re lucky, we’ll be in an all-out race with the CCP; if we’re unlucky, an all-out war.
Everyone is now talking about AI, but few have the faintest glimmer of what is about to hit them. Nvidia analysts still think 2024 might be close to the peak. Mainstream pundits are stuck on the wilful blindness of “it’s just predicting the next word”. They see only hype and business-as-usual; at most they entertain another internet-scale technological change.
Before long, the world will wake up. But right now, there are perhaps a few hundred people, most of them in San Francisco and the AI labs, that have situational awareness. Through whatever peculiar forces of fate, I have found myself amongst them. A few years ago, these people were derided as crazy—but they trusted the trendlines, which allowed them to correctly predict the AI advances of the past few years. Whether these people are also right about the next few years remains to be seen. But these are very smart people—the smartest people I have ever met—and they are the ones building this technology. Perhaps they will be an odd footnote in history, or perhaps they will go down in history like Szilard and Oppenheimer and Teller. If they are seeing the future even close to correctly, we are in for a wild ride.
Let me tell you what we see.

State of Artificial intelligence Report 2023
Artificial intelligence (AI) is a multidisciplinary field of science and engineering whose goal is to create intelligent machines.
We believe that AI will be a force multiplier on technological progress in our increasingly digital, data-driven world. This is because everything around us today, ranging from culture to consumer products, is a product of intelligence.
The State of AI Report is now in its sixth year. Consider this report as a compilation of the most interesting things we’ve seen with a goal of triggering an informed conversation about the state of AI and its implication for the future.
We consider the following key dimensions in our report:
Research: Technology breakthroughs and their capabilities.
Industry: Areas of commercial application for AI and its business impact.
Politics: Regulation of AI, its economic implications and the evolving geopolitics of AI.
Safety: Identifying and mitigating catastrophic risks that highly-capable future AI systems could pose to us.
Predictions: What we believe will happen in the next 12 months and a 2022 performance review to keep us honest.
Enhanced Enterprise Intelligence with your personal AI Data Copilot.pdf
Recently we have observed the rise of open-source Large Language Models (LLMs) that are community-driven or developed by the AI market leaders, such as Meta (Llama3), Databricks (DBRX) and Snowflake (Arctic). On the other hand, there is a growth in interest in specialized, carefully fine-tuned yet relatively small models that can efficiently assist programmers in day-to-day tasks. Finally, Retrieval-Augmented Generation (RAG) architectures have gained a lot of traction as the preferred approach for LLMs context and prompt augmentation for building conversational SQL data copilots, code copilots and chatbots.
In this presentation, we will show how we built upon these three concepts a robust Data Copilot that can help to democratize access to company data assets and boost performance of everyone working with data platforms.
Why do we need yet another (open-source ) Copilot?
How can we build one?

The Building Blocks of QuestDB, a Time Series Database
Talk Delivered at Valencia Codes Meetup 2024-06.
Traditionally, databases have treated timestamps just as another data type. However, when performing real-time analytics, timestamps should be first class citizens and we need rich time semantics to get the most out of our data. We also need to deal with ever growing datasets while keeping performant, which is as fun as it sounds.
It is no wonder time-series databases are now more popular than ever before. Join me in this session to learn about the internal architecture and building blocks of QuestDB, an open source time-series database designed for speed. We will also review a history of some of the changes we have gone over the past two years to deal with late and unordered data, non-blocking writes, read-replicas, or faster batch ingestion.

The Building Blocks of QuestDB, a Time Series Database
The Building Blocks of QuestDB, a Time Series Database
MANOVA paper review with example in R
- 1. ANLY 715 - Fangya Tan Paper Review: A Procedure Whose Time has Passed?
- 2. MANOVA: Multivariate analysis of variance Definition: Compare Multivariate Sample Mean (More than two DV) Application: Education, Psychology (25%) gifted education literature Challenges : Some paper using MANOVA for univariate research questions rather than multivariate questions.
- 3. • MANOVA + ANOVA Comb Multivariate effect - ANOVA (96%) HUBERTY AND MORRIS Truth : MANOVA + ANOVA is illogical Solution : MANOVA + DDA • Controlling Type I error rates when analyzing multiple DVs • Repeated Measures: Analyze repeated measurements taken from individuals over time (lab result, vital sign) Superior Choice: Linear Mixed Effects Model/ Multiple Imputation Bonus Application
- 4. • MANOVA Challenges • 1. The Actual research questions may not be multivariate to begin with • 2. Other statistical method can be better suited • 3. Some Assumptions are hard to Satisfied -Linearity of DV -homogeneity of covariance matrices (0.3-0.7) Out of Date?
- 5. • Independent random sampling • Linearity of the dependent variables (Pearson) • Multivariate normality(Kurtosis skewness) • Multivariate homogeneity of variance within groups (Levene’s test) • Multivariate homogeneity of variance between groups (Box M) Assumptions
- 6. ANOVA vs MANOVA Outcome Variable • Example: how children in public and private schools differ on three tests that measure (1) reading, (2) mathematics, and (3) moral reasoning • MANOVA : Whether groups differ on the variate (2 or more depend variables) Do children in public and private differ on a variate formed using three measured constructs? • ANOVA : Whether three or more groups differ on the mean of depend variable. Do children in public and private differ on mean value of Math/reading/reasoning scores?
- 7. Alternative Solution Maybe we can try something different! D Research Procedure to Consider Advantage Mean Differences between groups for DV Regression with corrections for multiple comparison Well understood Correct Type I error （Bonferoni） Latent Mean differences SEM structural equation modeling Devoid model error intercorrelations between DV Repeated Measures Mixed effect model Multiple computation Missing Data
