Question 1

Which of the following is NOT a problem caused by multicollinearity in multiple regression?

Accepted Answer

A)  The F-test of the overall multiple regression model may indicate a statistically significant relationship, but the t-tests for the individual coefficients may not indicate any as significant. 
B)  The regression coefficients can have a sign opposite that of the actual relationship. 
C)  It impacts the size of the R2 and the ability to predict values of the dependent variable. 
D)  With a high degree of collinearity we cannot rely on the individual coefficients to interpret the results. 
E)  All of these choices are problems caused by multicollinearity in multiple regression.
