Dear all, I found most of R packages do stepwise model selection with AIC criterian. I am doing a study on the comparison of severy popular model selection methods including stepwise using p-value criterian. We know that in SAS the stepwise uses p-value criterian, so this method could be a widely-used method. Does any one know in R which package has the stepwise using p-value criterian?
