Questiоn 1: Dаtа Explоrаtiоn (10 total points) For this question, use the trainData. (1a) (6 points) Create well-labeled stacked bar plots (and interpret each plot) showing the proportion of people who prefer remote work (in brown color) and people who do not prefer remote work (in blue color) for the following categorical variables: i) Country ii) JobRole. Make sure the proportion of the response variable "RemoteWorkPreference" is on the y-axis and the categorical variables on the x-axis. (1b) (4 points) What percentage of people in marketing prefer remote work? What is the mean and standard deviation of the age of the people in marketing who prefer remote work?
Questiоn 5: Predictiоn (12 tоtаl points) Note: Use "testDаtа" for all questions in Q5 5a)(4 points) Using testData and with the previously built models in Q2-4, predict the probability of remote work being preferred and output the average of these probabilities for each of the models below: i) Full Logistic regression model from question 2a (model1) ii) Decision tree model from question 2d (model2) iii) Stepwise regression model from question 3a (model3) iv) Ridge regression model from question 4a (model4) v) Group Lasso model from question 4b (model5) 5b)(3 points) Using the probabilities from Q5a, obtain the classifications of remote work being preferred for all five models using a threshold of 0.3. Show the last ten classification rows for all the models. 5c)(5 points) i) Using the classifications from Q5b, create a confusion matrix and output the classification evaluation metrics for all 5 models. ii) What metric is used to identify the true positive rate? Which model shows the highest value for this metric?
