I'm interested in the marginal effects so I'm using
the -dprobit- command. And I'm puzzled because the coefficients on
some of my explanatory dummy variables are greater than 1. I thought
that the coefficients represent the change in probability associated
with moving from dummy = 0 to dummy = 1, so they couldn't possibly be
greater than 1.
A marginal effect for a continuous variable is a slope and so can
be greater than 1. Here is an FAQ on the topic that explains
the issue in detail:
