Re: st: problems with installing the quaids command

[Marly Tatiana Celis Galvez <marlytati@gmail.com>]

Dear Statalisters,

I have been written my program quaids for nlsur command, I have had
some problems with the estimation procedure, in the output only 60 of
105 parameters are estimated, I don’t know if it is because of the
program I wrote or something else. I am not an expert in programing
STATA. What can I do? Wait for the next article of Brian Poi or
continue studying the STATA programming module? I appreciate any
advice.  Regards

Marly Tatiana Celis
