\section*{Maintainer's note}
This vignette reproduces the technical report

\emph{Schafer, J. L. (1998). Some Improved Procedures for Linear Mixed Models.
Department of Statistics, The Pennsylvania State University.}

The report is distributed with the \texttt{lmm} package for historical reference
and can be viewed from R with \texttt{vignette("lmm")}.

Table~\ref{tab:marijuana} reproduces the marijuana data used throughout the
report. The same data are included in the package and are used in the
accompanying examples.

\begin{table}[ht]
\centering
\small
\caption{Change in heart rate (beats per minute above baseline) measured
15 and 90 minutes after marijuana use. Missing values are denoted by ``--''.}
\label{tab:marijuana}

\begin{tabular}{crrrccc}
\toprule
& \multicolumn{3}{c}{15 minutes}
& \multicolumn{3}{c}{90 minutes} \\
\cmidrule(lr){2-4}\cmidrule(l){5-7}
Subject & Placebo & Low & High & Placebo & Low & High \\
\midrule
1 & 16 & 20 & 16 & 20 & -6 & -4 \\
2 & 12 & 24 & 12 & -6 & 4 & -8 \\
3 & 8 & 8 & 26 & -4 & 4 & 8 \\
4 & 20 & 8 & -- & -- & 20 & -4 \\
5 & 8 & 4 & -8 & -- & 22 & -8 \\
6 & 10 & 20 & 28 & -20 & -4 & -4 \\
7 & 4 & 28 & 24 & 12 & 8 & 18 \\
8 & -8 & 20 & 24 & -3 & 8 & -24 \\
9 & -- & 20 & 24 & 8 & 12 & -- \\
\bottomrule
\end{tabular}
\end{table}

After loading the package, run the example with
\texttt{example(example)}. The corresponding source code is available via
\texttt{help(example, package = "lmm")}.
