ppcheck

A fitted model object returned by one of the
<pkg>rstanarm</pkg> modeling functions. See <code><a href="/link/stanreg-objects?package=rstanarm&version=2.9.0-1" rd-options="" data-mini-rdoc="rstanarm::stanreg-objects">stanreg-objects</a></code>.

object

The type of plot (possibly abbreviated) to show. One of 
<code>"distributions"</code>, <code>"residuals"</code>, <code>"scatter"</code>, 
<code>"test"</code>. See Details for descriptions.

check

The number of $y^{rep}$ datasets to generate from the
posterior predictive distribution (<code><a href="/link/posterior_predict?package=rstanarm&version=2.9.0-1" rd-options="" data-mini-rdoc="rstanarm::posterior_predict">posterior_predict</a></code>) and
show in the plots. The default is <code>nreps=3</code> for
<code>check="residuals"</</code>

nreps

For <code>check="distributions"</code> only, should distributions be
plotted as density estimates overlaid in a single plot (<code>TRUE</code>, the 
default) or as separate histograms (<code>FALSE</code>)?

overlay

For <code>check="test"</code> only, a character vector (of length 1 or 
2) naming a single function or a pair of functions. The function(s) should 
take a vector input and return a scalar test statistic. See Details.

test

Optional arguments to geoms to control features of the plots 
(e.g. <code>binwidth</code> if the plot is a histogram).

ppcheck is deprecated and will be removed in the near future. Use
<code><a href="/link/pp_check?package=rstanarm&version=2.9.0-1" rd-options="" data-mini-rdoc="rstanarm::pp_check">pp_check</a></code> instead.

internal

Estimates pre-compiled regression models using the 'rstan' package, which provides
    the R interface to the Stan C++ library for Bayesian estimation. Users specify models via the
    customary R syntax with a formula and data.frame plus some additional arguments for priors.

ppcheck: ppcheck (deprecated)
