# Interpreting AIC forward stepwise function in R

• This is homework, so please add the self-study tag. – EdM Dec 2 '15 at 14:57
• Have you read about the AIC? Is there some particular statistical software that your instructor uses for "forward stepwise procedure with entry probability of 0.20"? Some software uses p-values for deciding whether to include a variable, but step in R does not. Do you understand the limits of stepwise selection, and how poorly the results tend to generalize to other samples from the same population? – EdM Dec 2 '15 at 15:23
