Hi Austin,
Not sure I understood.. my variables list include both "years_abroad"
and "ln_years_abroad" (which is just the ln of the previous. I specify
in the ivpois comand just the "ln_years_abroad" var. but somehow I
recieved estimates for both vars.
I ran the -ds- comand and both vars. appear .
Any idea what else can it be?
Many thanks
Anat
