This document discusses the assumptions of the classical linear regression model (CLRM) and methods for testing for violations of those assumptions. It covers the assumptions of no autocorrelation between error terms, homoscedasticity or constant error variance, and the errors having a normal distribution. Tests for heteroscedasticity discussed include the Goldfeld-Quandt test and White's test. Tests for autocorrelation examined are the Durbin-Watson test and Breusch-Godfrey test. Consequences of violations include inefficient coefficient estimates and invalid inferences. Potential remedies discussed include transforming variables or using heteroscedasticity-robust standard errors.

Common mistakes in measurement uncertainty calculationsGH Yeoh
The basic calculation for measurement uncertainty (MU) is through the law of propagation of uncertainty. Some find it difficult to apply and make some mistakes in the MU evaluation.
Take it to the Limit: quantitation, likelihood, modelling and other mattersStephen Senn
Taking the example of estimating parameter values when some observations are below the limit of quantitation I illustrate the utility of likelihood as a general framework for modelling. Some geometrical representations of this simple problem are considered and the way that the method of maximum likelihood delivers not only an estimate but an estimate of the reliability of the estimate is considered. I also discuss the importance of assumptions about how data come to be missing and some difficulties and limitations for more complex cases will also be touched on.
Brief notes on heteroscedasticity, very helpful for those who are bigners to econometrics. i thought this course to the students of BS economics, these notes include all the necessary proofs.

In today’s fast-changing business environment, it’s extremely important to be able to respond to client needs in the most effective and timely manner. If your customers wish to see your business online and have instant access to your products or services.
Online Grocery Store is an e-commerce website, which retails various grocery products. This project allows viewing various products available enables registered users to purchase desired products instantly using Paytm, UPI payment processor (Instant Pay) and also can place order by using Cash on Delivery (Pay Later) option. This project provides an easy access to Administrators and Managers to view orders placed using Pay Later and Instant Pay options.
In order to develop an e-commerce website, a number of Technologies must be studied and understood. These include multi-tiered architecture, server and client-side scripting techniques, implementation technologies, programming language (such as PHP, HTML, CSS, JavaScript) and MySQL relational databases. This is a project with the objective to develop a basic website where a consumer is provided with a shopping cart website and also to know about the technologies used to develop such a website.
This document will discuss each of the underlying technologies to create and implement an e- commerce website.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.
