If -gologit2- allows you to specify starting values, than you can set

Unfortunately, gologit2's programmer failed to build in such basic functionality. But I can speed things up a little bit by using ologit instead of gologit2 for the first part, i.e.

ologit y `x'
est store m1
gologit2 y `x', npl store(m2)
lrtest m1 m2, force
return scalar p = r(p)

It is running now so I will report back in a few months. If it takes too long, maybe I will just hack gologit2 to get the good start values. Rich
