st: mvprobit and changing results
Dear Statalist Users,
I use two do-files: the first one for generating the dataset from different
dta-files and the second one for running the data analysis focusing on a
mv-probit model drawing on the dataset generated from the first do-file.
I have just realised that every time I replace the previous dataset.file by
simply rerunning the first do-file the mv-probit results for exactly the
same model specifiaction change. Coefficients and standard errors vary
slightly, but the output for the correlation coefficients between error
terms change significantly (sometimes even from negative to positive
significance).
As the output for other estimation commands (reg, probit, etc.) does not
change I guess that this is due to the mvprobit. But I do not understand
what could be the reason for this.
Is there anyone having an idea what is going on?
I am grateful for any comments!
Thanks,
Ulf Narloch
