Hello,

I'm actually using the "Step" procedure in R for multiple regression analysis. I'm using the stepwise selection which alternates between forward selection and backward elimination (direction "both" in the step procedure). I would like to know which F-levels R is using to enter and then to remove variables?
I also would like which is the procedure to change such levels? For instance, how to use a critical/levels of 0.05/0.10?

Many thanks in advance!

Very sincerely,

Simon Blanchet
