My homework asks me to:
"Try a forward stepwise procedure with entry probability of 0.20. Then describe the model that is arrived at and whether it might be preferred."
I used the forward step function, starting off with a null model. Which is as below:
I am confused as to how to interpret this:
- What does the specific AIC values (87.08, 54.46 etc) mean?
- How is it related to p-values? Is entry probability referring to p-values?
- If AIC is not related to p-values, how can I interpret my model based on entry probability on R?
