\title{Class "Distribution"}
\description{ The \code{Distribution-class} is the mother-class of
class \code{UnivariateDistribution}.}
\section{Objects from the Class}{
Objects can be created by calls of the form \code{new("Distribution")}.
}
\section{Slots}{
\describe{
\item{\code{img}}{Object of class \code{"rSpace"}: the space of the image }
\item{\code{param}}{Object of class \code{"OptionalParameter"}: the parameter }
\item{\code{r}}{Object of class \code{"function"}: generates random numbers}
\item{\code{d}}{Object of class \code{"OptionalFunction"}: density function}
\item{\code{p}}{Object of class \code{"OptionalFunction"}: cumulative
distribution function}
\item{\code{q}}{Object of class \code{"OptionalFunction"}: quantile function}
\item{\code{.withArith}}{logical: used internally to issue warnings as to
interpretation of arithmetics}
\item{\code{.withSim}}{logical: used internally to issue warnings as to
accuracy}
\item{\code{.logExact}}{logical: used internally to flag the case where
there are explicit formulae for the log version of density, cdf, and
quantile function}
\item{\code{.lowerExact}}{logical: used internally to flag the case where
there are explicit formulae for the lower tail version of cdf and quantile
function}
\item{\code{Symmetry}}{object of class \code{"DistributionSymmetry"};
used internally to avoid unnecessary calculations.}
}
}
\section{Methods}{
\describe{
\item{img}{\code{signature(object = "Distribution")}: returns the space of
the image}
\item{param}{\code{signature(object = "Distribution")}: returns the
parameter}
\item{r}{\code{signature(object = "Distribution")}: returns the random
number generator }
\item{d}{\code{signature(object = "Distribution")}: returns the density
function }
\item{p}{\code{signature(object = "Distribution")}: returns the cumulative
distribution function }
\item{q}{\code{signature(object = "Distribution")}: returns the quantile
function}
\item{.logExact}{\code{signature(object = "Distribution")}: returns slot
\code{.logExact} if existing; else tries to convert the object to a newer
version of its class by \code{\link{conv2NewVersion}} and
returns the corresponding slot of the converted object.}
\item{.lowerExact}{\code{signature(object = "Distribution")}: returns slot
\code{.lowerExact} if existing; else tries to convert the object to a
newer version of its class by \code{\link{conv2NewVersion}} and
returns the corresponding slot of the converted object.}
\item{Symmetry:}{returns slot \code{Symmetry} if existing; else
tries to convert the object to a
newer version of its class by \code{\link{conv2NewVersion}} and
returns the corresponding slot of the converted object.}
