predict

Predictions after eintreg are described in

[ERM] eintreg predict predict after eintreg [ERM] predict treatment predict for treatment statistics [ERM] predict advanced predict’s advanced features

[ERM] eintreg predict describes the most commonly used predictions. If you fit a model with treatment effects, predictions specifically related to these models are detailed in [ERM] predict treatment. [ERM] predict advanced describes less commonly used predictions, such as predictions of outcomes in auxiliary equations.

Syntax for margins

margins [marginlist] [, options]

margins [marginlist] , predict(statistic ...) [predict(statistic ...) ...] [options]

statistic Description ------------------------------------------------------------------------- Main mean mean; the default pr probability of binary or ordinal y pomean potential-outcome mean te treatment effect tet treatment effect on the treated xb linear prediction pr(a,b) Pr(a < y < b) for continuous y e(a,b) E(y | a < y < b) for continuous y ystar(a,b) E(y*), y* = max{a,min(y,b)} for continuous y -------------------------------------------------------------------------

Statistics not allowed with margins are functions of stochastic quantities other than e(b).

For the full syntax, see [R] margins.

Description for margins

margins estimates margins of response for means, probabilities, potential-outcome means, treatment effects, and linear predictions.

Examples

Setup . webuse class10 . eintreg gpal gpau income, endogenous(hsgpa = income i.hscomp) . generate str name = "Billy" in 537

Expected values for college GPA if we fix Billy's hsgpa at 2.00 and at 3.00 and only consider his value of income . margins if name=="Billy", at(hsgpa=(2 3)) predict(fix(hsgpa))

Expected values for college GPA if we fix Billy's hsgpa at 2.00 and at 3.00 and if we also account for his values of hsgpa, hscomp, and unobservable factors that lead to correlation between hsgpa and college GPA . generate hsgpaT = hsgpa . margins if name=="Billy", at(hsgpa=(2 3)) predict(base(hsgpa=hsgpaT))
