\title{
Print a summary for a object of the "rregm" class.

\description{
Tools for a objects of the "rregm" class.
}
\usage{
res(object, type="pearson")
\method{AIC}{rregm}(object, ..., k=2)
\method{BIC}{rregm}(object, ...)
\method{coef}{rregm}(object, ...)
\method{logLik}{rregm}(object, ...)
\method{print}{rregm}(x, digits = max(3L, getOption("digits") - 3L), ...)
\method{summary}{rregm}(object, ...)
}
%- maybe also 'usage' for other objects documented here.
\arguments{
  \item{x, object}{
an object of the "rregm" class.
}
\item{type}{type of residuals to be presented: pearson (default), mod.pearson or quantile. 
}
\item{digits}{minimal number of significant digits
}
\item{k}{numeric, the penalty per parameter to be used; the default k = 2 is the classical AIC.
}
  \item{\dots}{
for extra arguments.}
}
\details{
Supported regression models are:
- reparametrized beta
- reparametrized gamma
- reparametrized beta prime
- reparametrized inverse gamma
