Question

(Circle the correct response) The distribution used when testing the statistical significance on an independent variable in a multiple regression is the a. Standard Normal distribution b.t - distribution c. F distribution d. chi^2 distribution (Circle all which apply) which of the following is a multiple linear regression model? a. y = b_0 + b_1 x_1 + b_2x_2 b. y = beta_0 + beta_1 x_1 + beta_2 x_2 + elementof c. y = b_1 x + b_2 x_2 + elementof d. y = beta_0 + beta_1 x^2_1 + beta_2x_2 (Circle the correct response) In multiple regression with 5 independent variables, the sum of squares due to error (SSE) is a. sigma (y_i - y_i)^2 b. sigma (y_i - y_i)^5 c. sigma (y_i - y_i)^2 d. sigma (x_i - y_i)^2 True or False: In multiple regression, the method of least squares minimizes the sum of squares due to error (SSE) (Circle the correct response) In multiple regression, a residual is a measure of point estimation error given by a.
