I am finding something bizzare in my -heckman- model and
wonder if anyone has a suggestion about what might be
I estimate the following model:
heckman Change_WRTm4 myvar $controls i1-i48 y1-y13,
twostep select(dummym1m3 = $FIRMm4 roa_m4 roa_m5 roa_m6)
The number of observations in this regression appears to be
around 6,000 but my "dummym1m3" (i.e., the dep. var. of the
selection equation) has only half as many 1's.
So, my question is - does Stata report the number of 0's
and 1's? I was expecting to see only the number of
An answer would be very helpful.
