Dear Gretl Community,
I'm trying to replicate the slope calculations that Gretl exhibits on Probit
estimation. In most of the time I can replicate exactly the same numbers,
but there are some cases that I can not (i.e. the values are different).
You're right, thanks for spotting this. Actually, the issue can be
replicated via a shorter script:
<hansl>
set messages off
set echo off
open greene19_1
probit GRADE GPA PSI
me = $coeff .* dnorm(meanc({$xlist})*$coeff)
printf "\nThe marginal effects:\n%12.8f", me
</hansl>
I'll try to see what happens asap.
