Dear Nick

Thanks very much for your help. I really appreciate it. It is probably a good idea to try other ways.

shows that -reoprob- is a user-written command from 2001, as you are asked to explain. I don't recall the author being active on Statalist for some years. You may have found a bug in -reoprob-, but you'd need to interact with the author directly, I suspect.

More positively, I suspect there are now other ways to get these models, but others can give better advice on that.

> I am trying to use -reoprob- for an ordered probit model for panel datasets. The model stopped when "Fitting constant-only model" and I got an error message saying "_00000Y not found", and the data for the dependent variable was changed. In my original data, I have five levels for pest pressure from 1 to 5, but now some of the "1" values are replaced with "zero". I looked at those cases where the data has been changed and I didn't see any structural difference. In addition to changing the data, the -reoprob-  command also added "group(_000006)" to label, which was previously empty. Could anyone shed some light on why the data was changed and a label was created? A previous post by J. Li in 2008 asked similar question about error message of "_00000W not found", but I don't see an answer to that particular question.
