\title{Rossi et al.'s Criminal Recidivism Data}
\description{
  This data set is originally from Rossi et al. (1980), and is used as an example
  in Allison (1995). The data pertain to 432 convicts who were released from
  Maryland state prisons in the 1970s and who were followed up for one
  year after release. Half the released convicts were assigned at random to
  an experimental treatment in which they were given financial aid; half did not
  receive aid.
