Re: st: sign of coefficients in a xtprobit

One of the first things I do when I see a dataset is use -fre- (you
can install that by typing in Stata -ssc install fre-) on the
variables I want to use. It just gives a frequency distribution but
also shows the numerical values and the value labels. Those three bits
of information can help you detect a lot of problems. Next step would
be to just look at a cross tabulation of your dependent and
independent variable using -tab x y, coll-.

Hope this helps,
