|Title||Stata7: Calculating the effects of dummy variables|
|Author||Ronna Cong, StataCorp|
By default, the marginal effect of a dummy variable x is calculated as the discrete change in F(x) as the dummy variable x changes from 0 to 1.
Marginal effect of x = F(x=1) - F(x=0)
If the nodiscrete option is specified, mfx will treat dummy variables as continuous ones.
