\title{Class "ChisqParameter"}
\description{ The parameter of a chi-squared distribution, used by Chisq-class}
\section{Objects from the Class}{
Objects can be created by calls of the form \code{new("ChisqParameter", ncp, df)}.
Usually an object of this class is not needed on its own, it is generated automatically when an object of the class Chisq
is instantiated.
}
\section{Slots}{
\describe{
\item{\code{ncp}}{Object of class \code{"numeric"}: the ncp of a chi-squared distribution }
\item{\code{df}}{Object of class \code{"numeric"}: the df of a chi-squared distribution }
\item{\code{name}}{Object of class \code{"character"}: a name / comment for the parameters }
}
}
\section{Extends}{
Class \code{"Parameter"}, directly.
}
\section{Methods}{
\describe{
\item{initialize}{\code{signature(.Object = "ChisqParameter")}: initialize method }
\item{df}{\code{signature(object = "ChisqParameter")}: returns the slot \code{df} of the parameter of the distribution }
\item{df<-}{\code{signature(object = "ChisqParameter")}: modifies the slot \code{df} of the parameter of the distribution }
\item{ncp}{\code{signature(object = "ChisqParameter")}: returns the slot \code{ncp} of the parameter of the distribution }
\item{ncp<-}{\code{signature(object = "ChisqParameter")}: modifies the slot \code{ncp} of the parameter of the distribution }
}
