Marginal Effects Continuous Variables
Categorical variables, such as psi, can only take on two values, 0 and 1. It wouldn’t make much sense to compute how P(Y=1) would change if, say, psi changed from 0 to .6, because that cannot happen. The MEM for categorical variables therefore shows how P(Y=1) changes as the categorical variable changes from 0 to 1, holding all
