Questiоn 4: Multicоllineаrity аnd оutliers. (12 points) 4а) (2 points) Diagnose multicollinearity in model2 created in Question 2b by calculating the Variance Inflation Factor (VIF) for each predictor. Based on the calculated VIF values, is multicollinearity a concern? 4b) (3 points) Use the Cook’s distance to count outliers in the data based on model2. i) Plot the Cook's distance for each observation. ii) Using the threshold 4/n, state clearly the number of outliers. 4c) (7 points) Remove the outliers (indicated in 4b) from the dataset "trainData". Create a linear regression model, using the dataset without the outliers. Use all the predictors. Call it model4. i) Compare the R-squared and adjusted R-squared values of model4 and model2. Which model performed better? ii) How does the presence or absence of these outliers affect the model’s regression coefficients? Do you observe any significant changes? Explain iii) What is the sampling distribution of the estimated regression coefficient corresponding to "Number of Rooms" in model4? iv) Is this estimated coefficient of "Number of Rooms" statistically significant at an alpha level of 0.01 in model4?
