BIOPROBIT: Stata module for bivariate ordered probit regression
Zurab Sajaia · RePEc: Research Papers in Economics · 2008
bioprobit fits maximum-likelihood two-equation ordered probit models of ordinal variables depvar1 and depvar2 on the independent variables indepvars1 and indepvars2. The actual values taken on by dependent variables are irrelevant, except that larger values are assumed to correspond to "higher" outcomes.
