If an additional variable causes a reduction in the adjusted multiple coefficient of determination, we have evidence that the new variable might not be worth keeping in the model.
True or false
Homework Answers
While the coefficient of determination always increases with addition of new variables in the regression model, the adjusted coefficient of determination may increase or decrease. An increase in adjusted coefficient of determination on addition of an additional independent variable indicates a better fit to the model than the previous one, while a reduction in adjusted coefficient of determination results in a worse fit. Therefore the given statement is True here.

Suppose you estimate a multiple regression model using OLS and the coefficient of determination is very high (above 0.8), while none of the estimated coefficients are (individually) statistically different from zero at the 5-percent level of significance. The most likely reason for this result is: multicollinearity. spurious regression. omitted variable bias. serial correlation.
