\title{Artificial Example for Binomial Regression}
\description{
	A simple artificial regression example data set with 3 latent
	classes, one independent variable \code{x} and a concomitant
	variable \code{w}.
}
\usage{data("BregFix")}
\format{
  A data frame with 200 observations on the following 5 variables.
  \describe{
    \item{\code{yes}}{number of successes}
    \item{\code{no}}{number of failures}
    \item{\code{x}}{independent variable}
    \item{\code{w}}{concomitant variable, a factor with levels \code{0} \code{1}}
    \item{\code{class}}{latent class memberships}
  }
