when an exogenous variable is a binary variable that is endogenous in the first equation, the resulting exogenous variable is x is a binary variable and is endogenous variable if used as an example what type of variable is an endogenous treatment effects variable what is endogenous treatment effect what variable is endogenous treatment effects is $y a continuous variable? what kind of variable is endogenous x is a determinant of which variable which is an exogenous variable? endogenous treatments definition which condition of a treatment effect is exogenous what is the determinant for $x$ in an endogenous treatment effect equation which of the following variable are exogenous covariates in an endogenous treatment effect model? endogenous treatment effects what is the relationship between endogenous effects and exogenous treatments? how to model endogenous disease which variable is exogenous? what is the exogenous variable x$ what is the first exogenous variable in the second equation that explains y$ which of the following is an endogenous variable
