runmlwin error with mlogit model

[juliettemalley]

Hi
I am trying to run a fairly simple model that I am struggling to get to converge in STATA using the gsem programme. When I try and run it using runmlwin I get the error message "error while obeying batch file C:\....temp at line number 19: NAME c6 'resp' c7 'resp_indicator' Duplicate column name.
The model code is: runmlwin resp cons, ///
level2(cassr: cons, residuals(u)) ///
level1(id:) ///
discrete(dist(multinomial) link(mlogit) denom(cons) basecategory(1)) ///
nopause
I've tried looking at the solutions to similar posts but I can't find anything that helps. Can you help?
thanks

Hi
i think I have managed to solve this. I renamed my dep var respond rather than resp and it now works. Am guessing somewhere in your code for the programme you use 'resp' to describe an output.

Yes, this would make sense. When MLwiN expands the data to "long" format for multivariate and multinomial models it creates new variables named resp and resp_indicator to contain the combined responses and which of the original responses each row belonged to.
