hello statalist,

i have attempted to use the mlogtest with iia option and hausman option, as well
as the manual hausman code (running 2 regressions) to get the above test
working. mlogtest says "you used the old syntax" of hausman and refers me to

hausman all partial, alleqs

which provides the following output(also when i use drop-down post-est menu);

no coefficients in common; specify equations(matchlist)
for problems with different equation names.

i've subsequently tried matching each category and had no luck

'Child' found where integer expected but when using integers, these are not
recognised and giving output "equation Child not found r(111);"

hausman all partial, equations(1:2)
equation at not found

i have a numeric floating 3-category dep var with "Child in school" "Child at
home" and "Child works"

shall i rename dependent variable ?
