Hi,I have a programming question. I want to run an alternative-specific conditional logit model (asclogit) with a casevars option that has a varying number of variables in the varlist. In particular, the varlist has up to four variables: age, gender, region, status. All are strings so dummies have to be created for each. I want the individual calls to asclogit to estimate a model with all four variables, with all combinations of three of the four, with two of the four, and with just one of each of the four. There are 2^4 = 16 combinations and hence 16 estimations. How can I write a program to loop through all 16 estimations? I want to avoid having to write out each of the 16.
Thanks, Walt ________________________ Walter R.
