\docType{class}

\alias{allcategorical_missing_data.frame-class}
\title{Class "allcategorical_missing_data.frame"}
\description{
This class inherits from the \code{\link{missing_data.frame-class}} but is customized for the situation where all the variables are categorical.
}
\section{Objects from the Class}{
Objects can be created by calls of the form \code{new("allcategorical_missing_data.frame", ...)}.
However, its users almost always will pass a \code{\link{data.frame}} to the
\code{\link{missing_data.frame}} function and specify the \code{subclass} argument.
}
\section{Slots}{
The allcategorical_missing_data.frame class inherits from the \code{\link{missing_data.frame-class}} and
has three additional slots
\describe{
\item{Hstar}{Positive integer indicating the maximum number of latent classes}
\item{parameters}{A list that holds the current realization of the unknown parameters}
\item{latents}{An object of \code{\link{unordered-categorical-class}} that contains
the current realization of the latent classes}
}
}
\details{
The \code{\link{fit_model-methods}} for the allcategorical_missing_data.frame class
implement a Gibbs sampler. However, it does not utilize any ordinal information that
may be available. Continuous variables should be made into factors using the
\code{\link{cut}} command before calling \code{\link{missing_data.frame}}.
