Hi all,
I am using -reoprob- to estimate a dynamic ordered probit panel data
model with random effects. The dependent variable is self-assessed
health status with 5 ranks and only the first lag is included in the
regressor list. I got some strange error message for some of my
regressions. The command I used is as following:
xi: reoprob $yvar hlthclag1 hlthclag2 hlthclag3 hlthclag5 agec genderc
i.area fsize birthage lnhincome schoolm2 schoolm3 schoolm4 schoolf2
schoolf3 schoolf4 pmkfe pmknm mlnhincome mschoolm mschoolf if
qpropeducu==1, i(persruk)
The error message showed up when fitting the constant-only model as
following:
__00000W not found
What might be the problem here? Thanks very much!
Daisy
