  1. “In both the logit and probit models all the regressors are involved in computing the changes in probability”
  2. “for the logit model the rate of change in the probability of an event happening is given by ßjPi (1-Pi), where ßj is the (partial regression) coefficient of the jth regressor. But in evaluating Pi, all the variables included in the analysis are involved”
  3. “In the probit model, the rate of change in the probability is somewhat complicated and is given by ßj f (Zi), where f (Zi) is the density function of the standard normal variable and Zi = ß1 + ß2X2i + ... + ßkXki, that is, the regression model used in the analysis”
