Stata 7: How does mfx calculate the marginal effects of dummy variables?
| Title | Stata7: Calculating the effects of dummy variables | |
| Author | Ronna Cong, StataCorp | |
| Date | May 2001 |
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.
