print {rstan}  R Documentation 
Print a summary for a fitted model represented by a stanfit
object
Description
Print basic information regarding the fitted model and
a summary for the parameters of interest estimated by the samples included
in a stanfit
object.
Usage
## S3 method for class 'stanfit'
print(x, pars = x@sim$pars_oi,
probs = c(0.025, 0.25, 0.5, 0.75, 0.975),
digits_summary = 2, include = TRUE, ...)
Arguments
x 
An object of S4 class 
pars 
A character vector of parameter names. The default is all parameters
for which samples are saved. If 
probs 
A numeric vector of quantiles of interest. The default is

digits_summary 
The number of significant digits to use when printing the summary, defaulting to 2. Applies to the quantities other than the effective sample size, which is always rounded to the nearest integer. 
include 
Logical scalar (defaulting to

Details
The information regarding the fitted model includes the number of iterations, the number of chains, the total number of saved iterations, the estimation algorithm used, and the timestamp indicating when sampling finished.
The parameter summaries computed include means, standard deviations (sd), quantiles, Monte Carlo standard errors (se_mean), split Rhats, and effective sample sizes (n_eff). The summaries are computed after dropping the warmup iterations and merging together the draws from all chains.
In addition to the model parameters, summaries for the
logposterior (lp__
) are also reported.
