A simple alternative to the linear probability model for binary choice models with endogenous regressors Christopher F Baum, Yingying Dong, Arthur Lewbel, Tao Yang It reviews the linear probability model and discusses alternative specifications of non-linear models. Using detailed examples, Aldrich and Nelson point out the differences among linear, logit, and probit models, and explain the assumptions associated with each.

The fact that we have a probit, a logit, and the LPM is just a statement to the fact that we don’t know what the “right” model is. Hence, there is a lot to be said for sticking to a linear regression function as compared to a fairly arbitrary choice of a non-linear one! Nonlinearity per se is a red herring. As for measurement error, we would welcome seeing more applied work taking this where g() is the probability density function underlying the model (Normal distribution in the Probit model case, while the logistic distribution in the logit model case). Now, according to Woolridge (2009), in the case of the probit model, the value of g(0) is given by:
