Exam 13: Multiple Regression Analysis

The F value that is used to test for the overall significance of a multiple regression model is calculated by dividing the mean square regression (MSreg)by the mean square error (MSerr).

A multiple regression analysis produced the following tables. Using α\alphaα = 0.01 to test the model, these results indicate that ____________.

The F value that is used to test for the overall significance of a multiple regression model is calculated by dividing the sum of mean squares regression (SSreg)by the sum of squares error (SSerr).

If we reject H0: β1= β2=0 using the F-test, then we should conclude that both slopes are different from zero.

A multiple regression analysis produced the following output from Excel. The coefficient of multiple determination is ____________.

In regression analysis, outliers may be identified by examining the ________.

The following ANOVA table is from a multiple regression analysis. Source F p Repression 3 1500 Error 26 Total 2300 The SSE value is __________.

A multiple regression analysis produced the following tables. For x1= 360 and x2 = 220, the predicted value of y is ____________.

In a multiple regression model, the proportion of the variation of the dependent variable, y, accounted for the independent variables in the regression model is given by the coefficient of multiple correlation.

The following ANOVA table is from a multiple regression analysis. Source F p Repression 3 1500 Error 26 Total 2300 The value of the standard error of the estimate se is __________.

Minitab and Excel output for a multiple regression model show the t tests for the regression coefficients but do not provide a t test for the regression constant.

The following ANOVA table is from a multiple regression analysis with n = 35 and four independent variables. Source F p Repression 700 Error Total 1000 The R2 value is __________.
