Computech Technologies should launch CBA & CFM or CPBA & CFM first to maximize profit and minimize risk. These combinations require the fewest number of students (around 23) to break even based on their costs. CBA & CFM is preferred because it requires around 3 students per course, which is a safe assumption for the untested brand.
A logistic regression model was created using 341 data points to predict enrollment in 3-month courses. The model found that only age was a significant predictor, with older customers less likely to enroll. The optimal model has a constant of 5.622 and an age coefficient of -0.133. This indicates the target profile for these short courses should be younger consumers.
Host pathogen interactions - This presentation is about the Host pathogen interaction played between bacteria virus and the human body and it also explains about the different protein and enzymes secreted by pathogens to cause infection and diseases in human like the release of endotoxin and exotoxin.
The point of interest of the approach is on development of sigma level with the aid of using QC story
which incorporates the best manipulate and quality improvement. All sorts of first-rate control efforts directly
enhance sigma level of components. Additionally, through decreasing the level of Defectives consistent with
defectives per million (DPM) which immediately affect to the sigma stage. Here, within the paper certain
technique will be discussed to address the problems and dreams which can be an improvement in sigma stage for
the shop and decreased DPM level will be done. In the course of machining operation, nos. of types of defects
would be happened. Categories those defects and after analyze a few standards could be made so that possibility
for going on the defects may be decreased and Sigma level might be improved. The getting to know of the quality
controls procedure has to be surpassed directly to everyone within the company. Total Quality Control can be
achieved by proper methodology and the initially start up for fully implementing TQM may take few months for
any company to claim to be a TQM company. Thereafter, the standardized procedures may have to be followed
by all concerned to retain the progress achieved.

Week 2 Individual Assignment 2: Quantitative Analysis of Credit -
Solution
s
This assignment is based on the data we used during our two live sessions, but it has been updated to include a splitting variable (credit2.xlsx). In the spreadsheet under the tab “Data," you will find data
pertaining to 1,000 personal loan accounts. The tab “Data Dictionary” contains a description of what the various variables mean.
As a part of a new credit application, the company collects information about the applicant. The company then decides an amount of the credit extended (the variable CREDIT_EXTENDED). For these 1,000 accounts, we also have information on how profitable each account turned out to be (the variable NPV). A negative value indicates a net loss, and this typically happens when the debtor defaults on his/her payments.
The goal in this assignment is to investigate how one can use this data to better manage the bank's credit extension program. Specifically, our goal is to develop a classification model to classify a new credit account as “profitable” or “not profitable." Secondly we want to compare its performance in the context of decision support to a linear regression model that predicts NPV directly.
Please answer all the questions. Supply supporting documentation and show calculations as
needed. Please submit a single, well-formatted PDF or Word file. The instructor should not need to go searching for your answers! In addition, please upload an Excel file with your model outputs – the file will not be graded, but will help the instructor give you feedback, if your model differs substantially from the solutions.
For extra assistance, you may want to access the tutorials located on the course resource center page.Data Preparation
The data preparation repeats the steps from the live session:
a) The goal is to predict whether or not a new credit will result in a profitable account. Create a new variable to use as the dependent variable.
b) Create dummy variables for all categorical variables with more than 2 values (or if you prefer, you can sort your variables into numerical and categorical when you run the model).
c) Split the data into 2 parts using the splitting variable that has been added to the data set. This is to ensure a more balanced split between the validation and training samples. Note that Analytic Solver Data Mining only allows 50 columns in the analysis, so leave out your base dummies (if you created them) when partitioning. After the data partition, you should have 666 rows in your training data and 334 in your validation data.
The Assignment
1. Applying Logistic Regression
If one fits a Logistic Regression Model using all the independent variables, one observes a) a gap in the classification performance between the training data and the validation data, and b) very
high p-values for some of the variables. The performance gap between the training and validation may be a sign of overfitting, and the high p-values may b ...

As part of our team's enrollment for Data Science Super Specialization course under UpX Academy, we submitted many projects for our final assessments, one of them was Telecom Churn Analysis Model.
The input data was provided by UpX academy and language we used is R. As part of the project, our main objective was :-
-> To predict Customer Churn.
-> To Highlight the main variables/factors influencing Customer Churn.
-> To Use various ML algorithms to build prediction models, evaluate the accuracy and performance of these models.
-> Finding out the best model for our business case & providing executive Summary.
To address the mentioned business problem, we tried to follow a thorough approach. We did a detailed level Exploratory Data Analysis which consists of various Box Plots, Bar Plots etc..
Further we tried our best to build as many Classification models possible which fits our business case (Logistic Regression/kNN/Decision Trees/Random Forest/SVM) and also tried to touch Cox Hazard Survival analysis Model. Later for every model we tried to boost their performances by applying various performance tuning techniques.
As we all are still into our learning mode w.r.t these concepts & starting new, please feel free to provide feedback on our work. Any suggestions are most welcome... :)
Thanks!!

In the Adani-Hindenburg case, what is SEBI investigating.pptxAdani case
Adani SEBI investigation revealed that the latter had sought information from five foreign jurisdictions concerning the holdings of the firm’s foreign portfolio investors (FPIs) in relation to the alleged violations of the MPS Regulations. Nevertheless, the economic interest of the twelve FPIs based in tax haven jurisdictions still needs to be determined. The Adani Group firms classed these FPIs as public shareholders. According to Hindenburg, FPIs were used to get around regulatory standards.

2. Problem Statement 1:Which two products the Company should
launch first, and why?
Computech Technologies (P) ltd should launch CPA & CFM or CPBA & CFM as
of now to maximize their profit and minimize risk.
Reason: Irrespective of any program they are incurring fixed cost of 2.1048
Cr INR. So, the decision to launch which two products directly depends on
variable cost of those two programs.
Now if we assumethat 3 month course can be done repeatedly 4 times in a
year in the existing infrastructure then for CBA faculty cost will be 440,000
INR for 3 month (110 hr. * 1000 INR per hr.*4 times in a year. So, revenue
from CBA per year per person is480,000 INR (120,000 * 4 Times a year).
For CBA+CFM,TC: 21,048,000 (FC) + 440,000 (VC for CBA) + 396,000 (VC for
CFM) = 21,884,000.Revenue from these two product will be 480,000 (CBA
for 1 yr.) + 480,000 (CFM for 1 yr.) = 960,000.
Break-Even Analysis: So, min no of students required for Break-Even
21,884,000 /960,000 = 22.796 ≈ 23.
In similar way min no of students required for all the combination can be
calculated. And the least no of students are coming for CBA+CAPB or
CBA+CFM. For detailed calculation see Appendix A.
Risk Aspect:for CBA+CFM combo 23 students required for whole year which
means 23/ (4*2)≈3 students per course which is a safe assumption.
Qualitative Analysis:As the BRAND is not established yet people won’t like
to invest 6.2 Lakh for 2 year course at first. So, it’s better to start with 3
month course and then after reasonable brand awareness they can launch
other long term product.

Problem statement 2:
Based on analysis of the research data provided by the Marketing research company, work out the profile
of the kind of Consumer, the Company must focus on.
Objective is to build a predictive logistic regression model which will help client to identify the customer profile.
For this as we have already seen that we are concerned about customer for only 3 month course
(CBA/CPBA.CFM) we have taken a sample of 341 data points which include all the data points who enrolled for
these three program also 74 randomly chosen data point who didn’t apply for any of the program.
On that sample points binary logistic regression is run and output is interpreted in the below section.
3
5. Here CBA is dependent variable with value 0 or 1 which represent customer will not Enroll (0) or Enroll (1) for
CBA/CPBA/CFM. All the other characteristics of the customer is taken as independent variable. Among these
apart from Salary, Work-Ex and Age all are categorical variable.
Forward LR method is taken as no prior research work has been done in this regard.
INTERPRETATION OF OUTPUT
Table1:341 sample points are taken. From the whole set of data for preparing logistic regression for
CBA/CPBA/CFM enrollment.

9. Table 8:-2Log-Likelihood (-2LL) has decreased significantly to 106.994 from the initial -2LL value of 359.301.
Lower value of -2LL is indicating that model is predicting more accurately as 2LL indicates unexplained data.

a. Estimation terminated at iteration number 5 because parameter estimates changed by less than .001.
b. Estimation terminated at iteration number 20 because maximum iterations has been reached. Final solution cannot be
found.
Table 9:At step 1 Age variable is included in the model. Wald statistic for Age is 65.499 with
significance label less than .001. Wald statistic follows a Chi square distribution and tells us bcoefficient of Age is significant. And co-efficient for Age (b1) = -0.113
Exp(B)= 0.893 which is less than 1 which indicates if Age increases probability for Enrollment
decreases. (If the value of Exp(B) would be greater than 1 then it would increase with increase in Age )
In Step 2, 3 and 4 Educational Qualification, Functional Area and Work-Ex is included but result is not
significant. So only step1 in considered. So, no other predictor is taken for the model.

10. Table 10:Change in -2LL for Age is 111.234 with significance label of <.001 which means it has a
significant effect on the predictive ability of the model.

11. This graph tells us how well the predictive model is. As max clusters are at each end the model and no of
N in right hand side and no of Y in left hand side is very less the model is reliable.
So, apart from age no other characteristics can be predicted as a significant predictor for the
logistic regression which will help client to identify customer profile.
Co-efficient of constant and Age (B0) and (B1) for the model is 5.622and -0.133 respectively.
