\title{bild: a package for BInary Longitudinal Data}
\description{
\code{bild} performs logistic regression for binary longitudinal
  data, allowing for serial dependence among observations from a given
  individual and a random intercept term. Estimation is via maximization
  of the exact likelihood of a suitably defined model. Missing values and 
  unbalanced data are allowed, with some restrictions. 
}
\details{This package contains functions to perform the fit of parametric models via likelihood method for binary
longitudinal data using "S4" classes and methods as implemented in the \code{methods} package.}
