This is the assignment, but I only really need D and E

PLEASE HELP

Identify most important variables using best subset algorithm to predict logarithm of housing prices using

three model selection criteria (rss = residual sum of square; adjr^2 = adjusted R^2 and bic =Bayesian

information criteria).

B. Provide descriptive statistics for identified important variables in Part 1 A.

C. Run multiple linear regression model with these identified variables (in Part 1 A). Write regression equation

and interpret any four regression coefficients.

D. Run multiple regression analysis with the variables identified in Part 1 with adding quadratic effects of

house size (SQFT) and provide average marginal effects (ame) with comments.

E. Plot and interpret prediction and average marginal effects of house size.
