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.
