Is there any way to perform stepwise Poisson regression with GEE in R? (I know, and agree that stepwise procedures are not best statistical practice. I have developed a model with 10 independent variables, my client want me to include 50 other independent variables. I, of course, don't what to do this. I am hoping that I can demonstrate that adding additional variables does not make a material change to the results, but I don't want to have to perform this arduous task by hand). Thank you, John
