Questiоn 3: Mоdel Diаgnоstics (10 points) (3а) (3 points) Perform diаgnostic checks for the model1 created in Question 2.i) Check for constant variance using visual/plots. Explain your findings.ii) Check for normality using visuals/plots. Explain your findings. (3b) (2 points) Check the model1 for multicollinearity using variance inflation factor (vif). Is multicollinearity a problem. Explain your conclusion. (3c) (2 points) Use the Cook’s distance to count outliers in the data based on model1 from Question 2. Any observation with a Cook’s distance larger than 4/n should be considered as an outlier. i) State clearly the number of outliers. ii) Also show the indices of the outliers (You don't have to write the indices separately, just show the output) (3d) (3 points) Remove the outliers from the dataset and again fit a multiple linear regression model on the "cleaned" (without outliers) dataset. i) Display the summary. Call it model2ii) Is there a difference between model1 and model2. Do you see any improvement? Explain with reasoning.iii) Are the outliers influential? Explain
