Fitting exogenous probit model
Did you know?
WebThe probit model A) is the same as the logit model. B) always gives the same fit for the predicted values as the linear probability model for values between 0.1 and 0.9. C) forces the predicted values to lie between 0 and 1. D) should not be used since it … 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.
