B) Some of the residual plots for the regression of PSA on the other variables may be found on p. 5 of the computing handout.

B) Some of the residual plots for the regression of PSA on the other variables may be found on p. 5 of the computing handout. For each of the 4 plots, state what the plot should look like if the model fits well, and note any violations. C) The partial leverage plot for VOL may be found on p. 6 of the computing handout. How does this plot differ from a residual plot? D) Part of the ANOVA table for the model may be found below. Fill in the blanks. E) What is the R2 for the model? G. What is the R2 of the model with only VOL, WT and AGE? H. The plots of leverage and Cook"s distance versus AGE are on p. 7 of the computing handout. Are there any high leverage points or extraordinarily influential points? Briefly justify your answer. I. The Variance inflation factors are below. Are there any problems of multicollinearity?
