= Bivariate probit model for endogenous treatment

A bivariate probit model for a binary treatment and outcome uses latent equations
$$
A=\mathbf1_{\{X^T\alpha+U>0\}},\qquad
Y=\mathbf1_{\{A\beta+X^T\gamma+V>0\}},
$$
where $(U,V)$ has a <bivariate normal distribution>. Its correlation parameter represents dependence between the two latent disturbances; when nonzero, treatment is endogenous in the outcome equation.
