Thanks! I think -treatreg- does something different, isn't it like
"heckman" command.
I want to first create a treated group and a comparable control group
(countries that are in the list of poor countries v.s. non-poor countries),
then select them to low/high GDP growth rate countries, and finally, see how
such a selection into poor/low growth (poor/high growth) affects the
relationship between growth and explanatory variables. I was instructed to
read Heckman et al (1997) "Matching as an Evaluation Estimator" for the case
of participation in job training and apply the same method to my case.
That's why I thought -match- could be a command to start with. Isn't clogit
something similar to match? Or would you still suggest -treatreg-?
Thank you!
Katharina
