<> What happens if you run the examples in the do-files shipped with the package? Use -findit stgest- to find them. I know it sounds trite, but if they do run, and yours don`t, you have to find a difference in the setup that leads to the problems...

Juni 2010 15:32 An: statalist@hsphsun2.harvard.edu Betreff: Re: st: RE: RE: RE: RE: error messages while using the stgest command Regarding the first error, I included no graph options in my instructions. This is exactly what I typed: stgest diabetes cursmoke agebase sex hyperten obese, lagconf(hyperten obese diabetes) baseconf(hyperten obese diabetes) /* */ visit(visit) firstvis(2) (lasttime(endfudate) range(-50 50) step(1) saveres(caergestsmoknocens) replace I tried with two different datasets and got the same error. Regarding the second error, I did run a Weibull model before running gesttowb. This is what I typed: weibull _t diabetes B* L* if visit>=2, dead(_d) t0(_t0) hr gesttowb Victor.
