The t-test in the multiple regression model:
(A) is used to test the presence of measurement errors in the data.
(B) is used to test for the presence of a non-linear relationship.
(C) is used to test the significance of all dependent variables.
(D) is used to test the significance of one dependent variable.
(E) none of the above is correct.
Homework Answers
Answer
The correct answer is (E) none of the above is correct.
The t test in the multiple regression model is used to check whether the independent variable has significant impact on the dependent variable. Thus t test in the multiple regression model is used to test the significance of an independent variable and not dependent variable.
Hence, the correct answer is (E) none of the above is correct.

How does a bivariate regression model differ from a multiple regression model? Multiple Choice A bivariate regression has only one dependent and independent variable but a multiple regression has one dependent variable and may have many independent variables. A bivariate regression has more than one dependent variable and only one independent variable where a multiple regression has one dependent variable and may have many independent variables. A bivariate regression has only one dependent and many independent variables but a multiple...

1) In a multiple regression output, if individual test of slope coefficient for each variable shows that all the independent variables are not significant individually, but test on overall validity of model supports the alternative hypothesis at a specified level of significance, this is most likely due to: A. autocorrelation B. multicollinearity C. the presence of dummy variables D. the absence of dummy variables 2.

(b) (1 mark) In the multiple regression model, the assumption of no perfect collinearity is best described as: i. The explanatory variables will not be correlated at all. ii. The explanatory variables will have correlation coefficients close to one. iii. None of the explanatory variables will be an exact linear combination of the other explanatory variables. iv. The dependent variable will not be correlated with the explanatory variables.
