The print method for stanreg objects displays a compact summary of the
fitted model. See the Details section below for descriptions of the
different components of the printed output. For additional summary statistics
and diagnostics use the summary method.
# S3 method for stanreg
print(x, digits = 1, detail = TRUE, ...)# S3 method for stanmvreg
print(x, digits = 3, ...)
Returns x, invisibly.
A fitted model object returned by one of the
rstanarm modeling functions. See stanreg-objects.
Number of digits to use for formatting numbers.
Logical, defaulting to TRUE. If FALSE a more
minimal summary is printed consisting only of the parameter estimates.
Ignored.
Regardless of the estimation algorithm, point estimates are medians computed
from simulations. For models fit using MCMC ("sampling") the posterior
sample is used. For optimization ("optimizing"), the simulations are
generated from the asymptotic Gaussian sampling distribution of the
parameters. For the "meanfield" and "fullrank" variational
approximations, draws from the variational approximation to the posterior are
used. In all cases, the point estimates reported are the same as the values
returned by coef.
The standard deviations reported (labeled MAD_SD in the print output)
are computed from the same set of draws described above and are proportional
to the median absolute deviation (mad) from the median.
Compared to the raw posterior standard deviation, the MAD_SD will be
more robust for long-tailed distributions. These are the same as the values
returned by se.
For GLMs with group-specific terms (see stan_glmer) the printed
output also shows point estimates of the standard deviations of the group
effects (and correlations if there are both intercept and slopes that vary by
group).
For analysis of variance models (see stan_aov) models, an
ANOVA-like table is also displayed.
For joint longitudinal and time-to-event (see stan_jm) models
the estimates are presented separately for each of the distinct submodels.
