Select all true statements about the diagnostic measures (i. e., measures of goodness of fit). Note: In all cases, assume the same set of sample data is used. a. Adding more predictors to the model will never lead to a larger standard error (s).
b. Adding more predictors to the model will never lead to a decrease in R2.
c. One of the most important aspects of the adjusted R2 is that it allows us to compare models with a different number of variables involved.
d. Using the adjusted R2 is important when comparing models with different sample sizes. The number of predictors is irrelevant.
e. Adjusted R2 is always smaller than the unadjusted R2
f. Adjusted R2 helps the researcher in the goal of parsimony (i. e., keeping the model as simple as pos
