In the probit model, the inverse standard normal distribution of the probability is modeled as a linear combination of the predictors. Probit and logit models in r econometricsmodelsprobitandlogitmodels. The book suggests to use the method that is easiest to use in the statistical software of choice. The model will be saved in the working directory under the name logit. Specifying a probit model is similar to logistic regression, i. This is almost surely a newbish question for the dataset below i have been trying to plot both the logit and the probit curves in ggplot2 without success. Probit model, predicted probabilities and estimated effects. This program estimates the full covariance matrix subject to normalization.
