Fitting exogenous probit model
WebBoth can be called variants on the probit model, but theta parameterization corresponds more exactly to the probit regression estimates in which the . y * distribution is assumed to be standardized. These scaling choices are arbitrary in the sense that the chi-square for the model and the significance tests of the parameter estimates will be equal. WebThe method is very simple: Fit the first-stage model to get the residual and include both the residuals and the endogenous variable in the second-stage model. Or more formally, let $𝑦_2$ be the endogenous variable, $𝑥_1$ till $𝑥_8$ the other exogenous control variables and $𝑖_1$ and $𝑖_2$ two instruments for $𝑦_2$.

WebJul 24, 2024 · As both @Dimitris Rizopoulos and @Jeremy Miles say, it is possible to fit an SEM using categorical data (i.e., which includes your dichotomous and ordinal variables). There are generally two methods used to go about doing this 1. The first is the direct method, which treats categorical data as continuous and, as a result, estimates model ...
