In the above example, we demonstrated that the value y (above the table in the mfx output) is the value you obtain when you predict at the average values of the covariates and the average value of the offset. In the next example, we will go further and calculate the marginal effects of...

Let’s see an example of marginal effects. Because of Stata’s factor-variable features, we can get average partial and marginal effects for age even when age enters as a polynomial: .webuse nlsw88, clear(NLSW, 1988 extract) .quietly probit union wage c.age c.age#c.age collgrad . mar...
StataRandom effects probit and logit are nonlinear models, so we need predicted probabilities and marginal effects to communicate the economic significance of results. In these calculations, how one treats the individual-specific error term matters. Should one (i) set them equal to zero or (ii) ...

First, I implemented bias-corrected probit and logit binary response models with two-way fixed effects, following the strategy developed by Stammann et al. (2016), and found that the sign of the results for the binary response model remains stable when nonlinear models are adopted, although ...
