HEY GUZ CAN U PLZ HELP ME ON THSES @ PROBLEMS< PLZZZ.



1. Please derive solution of parameter estimation for Multiple Linear Regression Model. [(X’X) –1X’Y]. Please also show that the solution is the same as the previous solution in Simple Linear Regression. (2pt for the total score)
2. Since Stepwise Linear Regression is a greedy search algorithm, please construct the examples that the model found by Stepwise Linear Regression is not the best among all possible models with the same number of predictors. Please explain how you construct such a example.

thanks!
