BTW, quite apart from the technical aspects of capturing the coefficients,
does it make sense to put the same variable into the -by- prefix and the
-group()- option? It leads to no good in this example, for one:
*************
webuse lowbirth2, clear
bys pairid: clogit low lwt smoke /*
*/ ptd ht ui i.race, /*
*/ group(pairid)
*************

Betreff: st: including "gen" in a "by"-command
Dear Statalist,
I would like to conduct a clogit seperated by each household. So far so
good. My syntax is as follows:
sort hhnr
by hhnr: clogit DV IV1 IV2, group(hhnr)
Now as I am getting the beta coefficients for each household I would like to
add them as a variable to each household. Following syntax is not really
working, it just adds the last calculated beta coefficients to all
households:
gen b1=_coef[ri]
gen b2=_coef[ri2]
Is there any possibility to include the gen command in the by command?
Your help as much appreciated.
Thanks a lot,
Regina
