Consider the following responses and the associated values of the explanatory vari- ables: Response YX₁ X₂ X3 1 -1 2 1 -1 -3 1 0 -4 0 1 -3 -1 2 0 -1 3 5 3 4 5 6 (X'X)-¹ = 1 0 -2 do 0 1 2 3 12 5 0 Based on the conventional notations for the multiple regression model we have X'Y = [10, 14, 10, -3]', and 00 00 0 0 00 00 0 (a) Specify the multiple regression equation to represent the data and state all the assumptions for the associated multiple regression model. (b) Find an estimator for the regression vector 3 = [Bo, B₁, B₂, B₁l' and write the equation for the fitted multiple regression line. (c) Predict the value of Y when z₁ = 1, 7₂ = −3, 73 = −1. Why is the predicted value different from the observed value of Y = 2?
