Greetings-
I am seeking to fit a model using Heckman-style selection; however the
wrinkle is that the selection is into multiple categories, not a binary
in/out. In this case, selection is into the type of higher-education
institution a student attended; the goal is to estimate post-graduation
outcomes while correcting for selection into universities.
There is an old Stata file, svyselmlog, that may or may not solve this
problem in stata. Any guidance or pointers toward solving it in R would
be most welcome.
Thanks-
Andy Perrin
