Say, union in my example is wage in yours and grade in my example is
depression in yours.

*------------------ begin example ------------------
sysuse nlsw88, clear
gen byte miss = missing(union)

logit miss grade
predict pr

logit mis i.grade
testparm i.grade

collapse (mean) miss pr, by(grade)

twoway line miss pr grade
*------------------- end example -------------------

Hope this helps,
