Hi Austin,

I tried your suggested code and I am getting an error r(2000) which means no
observations.

Could it be because the line: loc j=`j'-14 starts without indicating what
the starting value of j is? 

I tried loc j=`i'-14 but that also returned the same error with no
observations.

Thanks for your help

Ariel

Probably you are not running any logits. Maybe you want:

g double ps=.
forv i=14/24 {
 loc j=`j'-14
 logit Y l(0/`j').X1 l(0/`j').X2 l(0/`j').X3 if month==`i'
 tempvar w
 predict double `w'
 replace ps=`w' if e(sample)
 drop `w'
}
