st: RE: -reoprob- error: "varlist required"

[Nick Cox <n.j.cox@durham.ac.uk>]

-reoprob- is a user-written command, as you are asked to explain.

The syntax of -reoprob- is that you should specify -i()-. 

You specified -id()- instead and -reoprob- stopped when that became problematic. 

The wrong option -id()- is not caught as such because -reoprob- allows a bundle of extra options to pass to -ml-.

I am running an ordered probit panel regression model with random
effects (reoprob) of health self-assessment variable (health1) on
gender (ahgsex) with 8 time periods and ID as a panel personal
identifier. The panel is balanced, there are 4 categories in health1,
ahgsex is a dummy which is equal to 1 for men. I get an error -
varlist required- (see below).
. reoprob health1 ahgsex, id( ID)
varlist required
r(100);

I tried renaming the variables, including different independent
variables, but still get the same error. I use Stata 11.
Could someone please advise how I can tackle this problem?
