Hi all, I'm Yago again. So I'm struggling with a new thing. The script I'm writing asks the user to imput at the very top what variables will be used as dependent and regressors for a logit model. I wanted to put it at the top so any user imput is close and neat, and there's no skim through code necessary. The problem is that I can't make a list before I have a dataset, I can't make a list for series that are not defined before such list.
