\title{Class "CompoundDistribution"}
\description{\code{CompoundDistribution}-class is a class to formalize
compound distributions; it is a subclass to
class \code{UnivarMixingDistribution}.}
\section{Objects from the Class}{
Objects can be created by calls of the form
\code{new("CompoundDistribution", ...)}.
More frequently they are created via the generating function
\code{\link{CompoundDistribution}}.
}
\section{Slots}{
\describe{
\item{\code{NumbOfSummandsDistr}}{Object of class \code{"DiscreteDistribution"},
the frequency distribution.}
\item{\code{SummandsDistr}}{Object of class \code{"UnivDistrListOrDistribution"},
that is, either of class \code{"UnivarDistrList"} (non i.i.d. case) or
of class \code{"UnivariateDistribution"} (i.i.d. case); the summand distribution(s).}
\item{\code{mixCoeff}}{Object of class \code{"numeric"}: a vector of
probabilities for the mixing components.}
\item{\code{mixDistr}}{Object of class \code{"UnivarDistrList"}: a list of
univariate distributions containing the mixing components; must be of same
length as \code{mixCoeff}.}
\item{\code{img}}{Object of class \code{"Reals"}: the space of the image of this distribution which has dimension 1
and the name "Real Space" }
\item{\code{param}}{Object of class \code{"Parameter"}: the parameter of this distribution, having only the
slot name "Parameter of a discrete distribution" }
\item{\code{r}}{Object of class \code{"function"}: generates random numbers}
\item{\code{d}}{fixed to \code{NULL}}
\item{\code{p}}{Object of class \code{"function"}: cumulative distribution function}
\item{\code{q}}{Object of class \code{"function"}: 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{Extends}{
Class \code{"UnivarMixingDistribution"}
class \code{"UnivarDistribution"} by class \code{"UnivarMixingDistribution"},
class \code{"Distribution"} by class \code{"UnivariateDistribution"}.
}
\section{Methods}{
\describe{
\item{show}{\code{signature(object = "CompoundDistribution")} prints the object}
\item{SummandsDistr}{\code{signature(object = "CompoundDistribution")} returns the corresponding slot}
\item{NumbOfSummandsDistr}{\code{signature(object = "CompoundDistribution")} returns the corresponding slot}
}
}
\section{setAs relations}{
There is a coerce method to coerce objects of class \code{"CompoundDistribution"} to
class \code{UnivarLebDecDistribution}; this is done by a simple call to \code{simplifyD}.
