WebProbit regression. Probit analysis will produce results similar logistic regression. The choice of probit versus logit depends largely on individual preferences. OLS regression. When used with a binary response variable, this model is known as a linear probability model and can be used as a way to describe conditional probabilities. In probability theory and statistics, the probit function is the quantile function associated with the standard normal distribution. It has applications in data analysis and machine learning, in particular exploratory statistical graphics and specialized regression modeling of binary response variables. Mathematically, the probit is the inverse of the cumulative distribution function o…

Webpractice, the linear probability model is estimated by ﬁtting a straight line to the observations on X and Y by ordinary least squares. The ordinary least squares– based predictions of the conditional probability can be greater than one or less than zero. The logit and probit models are typically estimated by maximum likelihood.
