| Subject | st: zero-inflated negative binomial option for heckman in GLLAMM |
| Date | Thu, 12 Jul 2012 10:55:17 -0700 (PDT) |
Hi all, I know that a heckman model can be run in gllamm, and a Poisson distribution can be declared for the "y" dependent variable. I'd actually prefer zero inflated negative binomial, though. Is a zero-inflated option available for the final second-stage y for a heckman in gllamm? How would I declare this with the link and family options? Thanks!
