Re: st: survival analysis

[Johannes Schoder <johannes.schoder@soi.uzh.ch>]

Hi Marten:

Thanks for your help. However, when I am using your command Stata 
complains that "weights must be stset".
Therefore I used:
stset time_in_months [weight=freq], failure(vital)

This works out. However I can't use aweight Stata automatically uses 
fweight, if you should know how to actually tell Stata to use aweights I 
would be very happy for any hints.

Thanks,
Johannes
