\begin{Description}\relax
The \code{Oxboys} data frame has 234 rows and 4 columns.
\end{Description}
\begin{Format}\relax
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.

}
\end{Format}
\begin{Details}\relax
These data are described in Goldstein (1987) as data on the
height of a selection of boys from Oxford, England versus a
standardized age.
