## Stata 15 help for glogit_postestimation

```
blogit, bprobit, glogit, and gprobit continue to work but, as of Stata
14, are no longer an official part of Stata.  This is the original help
file, which we will no longer update, so some links may no longer work.

See glm postestimation for a recommended alternative.

Title

[R] glogit postestimation -- Postestimation tools for glogit, gprobit,
blogit, and bprobit

Description

The following postestimation commands are available after glogit,
gprobit, blogit, and bprobit:

Command            Description
-------------------------------------------------------------------------
contrast         contrasts and ANOVA-style joint tests of estimates
* estat ic         Akaike's and Schwarz's Bayesian information criteria
(AIC and BIC)
estat summarize  summary statistics for the estimation sample
estat vce        variance-covariance matrix of the estimators (VCE)
estimates        cataloging estimation results
lincom           point estimates, standard errors, testing, and
inference for linear combinations of coefficients
* lrtest           likelihood-ratio test
margins          marginal means, predictive margins, marginal effects,
and average marginal effects
marginsplot      graph the results from margins (profile plots,
interaction plots, etc.)
nlcom            point estimates, standard errors, testing, and
inference for nonlinear combinations of coefficients
predict          predictions, residuals, influence statistics, and
other diagnostic measures
predictnl        point estimates, standard errors, testing, and
inference for generalized predictions
pwcompare        pairwise comparisons of estimates
test             Wald tests of simple and composite linear hypotheses
testnl           Wald tests of nonlinear hypotheses
-------------------------------------------------------------------------
* estat ic and lrtest are not appropriate after glogit and gprobit.

Syntax for predict

predict [type] newvar [if] [in] [, statistic]

statistic          Description
-------------------------------------------------------------------------
Main
n                predicted count; the default
pr               probability of a positive outcome
xb               linear prediction
stdp             standard error of the linear prediction
-------------------------------------------------------------------------
These statistics are available both in and out of sample; type predict
... if e(sample) ... if wanted only for the estimation sample.

Options for predict

+------+
----+ Main +-------------------------------------------------------------

n, the default, calculates the expected count, that is, the estimated
probability times pop_var, which is the total population.

pr calculates the predicted probability of a positive outcome.

xb calculates the linear prediction.

stdp calculates the standard error of the linear prediction.

Syntax for margins

margins [marginlist] [, options]

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

statistic          Description
-------------------------------------------------------------------------
n                  predicted count; the default
pr                 probability of a positive outcome
xb                 linear prediction
stdp               not allowed with margins
-------------------------------------------------------------------------

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

For the full syntax, see [R] margins.
