\usage{
mcse(model, ...)

\method{mcse}{stanreg}(
  model,
  effects = c("fixed", "random", "all"),
  component = c("location", "all", "conditional", "smooth_terms", "sigma",
    "distributional", "auxiliary"),
  parameters = NULL,
  ...
)
}
\arguments{
\item{model}{A \code{stanreg}, \code{stanfit}, or \code{brmsfit} object.}

\item{...}{Currently not used.}

\item{effects}{Should results for fixed effects, random effects or both be
returned? Only applies to mixed models. May be abbreviated.}

\item{component}{Should results for all parameters, parameters for the
conditional model or the zero-inflated part of the model be returned? May
be abbreviated. Only applies to \pkg{brms}-models.}

\item{parameters}{Regular expression pattern that describes the parameters
that should be returned. Meta-parameters (like \code{lp__} or \code{prior_}) are
filtered by default, so only parameters that typically appear in the
\code{summary()} are returned. Use \code{parameters} to select specific parameters
for the output.}
}
\description{
This function returns the Monte Carlo Standard Error (MCSE).

\details{
\strong{Monte Carlo Standard Error (MCSE)} is another measure of
accuracy of the chains. It is defined as standard deviation of the chains
divided by their effective sample size (the formula for \code{mcse()} is
from Kruschke 2015, p. 187). The MCSE \dQuote{provides a quantitative
suggestion of how big the estimation noise is}.
