Dear List, I have a question regarding following problem, it would be amazing if anybody knows a solution. I am using prvalue to estimate the difference in the probability between 2 situations. However, the function is nonlinear (cubic) and I implemented a loop to do that. My problem now is that rest(grmean) is not working with the loop, does anybody know by any chance a work-around?

I wonder if life wouldn't be a lot easier if you used the -margins- command.
