Dear All,

I have a question on the interpretation of marginal effects calculated in
Stata from running a probit.

For example

I have a marginal effect of 0.429 - what does this mean?
Does this mean that for a 1 unit change in the independent variable, the
probability of the dependent variable taking a value of 1 increases by
42.9%? If so, I am unsure of what this 1 unit change is because some of my
independent variables are scaled and less than 1.

I would be greatful for any pointers

Regards

Daniel
