prchange is part of Long & Freese's -spost9- package and can be located via -findit-. I know what their routines often do is create and temporarily append fake cases to the data set, where these cases have the desired values, e.g. a half sd above the mean or a half sd below the mean. Their commands then use predict commands to get the predicted probabilities for these cases.Dear Statalisters, I would appreciate if anybody could let me know whethere there is anything like "prchange" commnad after ivprobit in STATA 9. I am trying to estimate the size-effect of some independent variables on the dependent one (e.g. the effect of minus/plu 1/2 standard deviation below and above the mean of the key independent variables on the probability that an event occurs), but I have been unable to work out how to do it after "ivprobit". Suggestions are welcome!

Also, sometimes you can use the -adjust- command for similar purposes.

I describe similar procedures on pp. 7-10 of

http://www.nd.edu/~rwilliam/stats2/Logistic-Stata9.pdf

Whether ivprobit raises some sort of special concerns that make the procedure more complicated or inappropriate, I don't know.
