\title{Heights of Boys in Oxford}
\description{
The \code{Oxboys} data frame has 234 rows and 4 columns.
}
\format{
This data frame contains the following columns:
\describe{
\item{Subject}{
an ordered factor giving a unique identifier for each boy in
the experiment
}
\item{age}{
a numeric vector giving the standardized age (dimensionless)
}
\item{height}{
a numeric vector giving the height of the boy (cm)
}
\item{Occasion}{
an ordered factor - the result of converting \code{age} from a
continuous variable to a count so these slightly unbalanced
data can be analyzed as balanced.
}
}
}
\details{
These data are described in Goldstein (1987) as data on the
height of a selection of boys from Oxford, England versus a
standardized age.
