Solutions

Expert Solution

Step 1:

The Linear Regression Model is given by:

                                      i = 1,2,...n

where

is response (dependent) variable

is predictor (independent) variable

is error

a = itercept

b = slope

Step 2:

Total Variation:

Step 3:

Variation explained by Linear Model:

Step 4:

Step 5:

When we estimate a linear multiple regression model (including a linear simple regression model), it appears that the calculation of the coefficient of determination, R2, for this model can be accomplished by using the squared sample correlation coefficient between the original values and the predicted values of the dependent variable of this model. Is this statement true? If yes, why? If not, why not? Please use either matrix algebra or algebra to support your reasoning.
