+    """HH: Statistical Analysis and Data Display: Heiberger and Holland.
+
+    Support software for Statistical Analysis and Data Display (Second
+    Edition, Springer, ISBN 978-1-4939-2121-8, 2015) and (First Edition,
+    Springer, ISBN 0-387-40270-5, 2004) by Richard M. Heiberger and Burt
+    Holland. This contemporary presentation of statistical methods features
+    extensive use of graphical displays for exploring data and for displaying
+    the analysis. The second edition includes redesigned graphics and
+    additional chapters. The authors emphasize how to construct and interpret
+    graphs, discuss principles of graphical design, and show how accompanying
+    traditional tabular results are used to confirm the visual impressions
+    derived directly from the graphs. Many of the graphical formats are novel
+    and appear here for the first time in print. All chapters have exercises.
+    All functions introduced in the book are in the package. R code for all
+    examples, both graphs and tables, in the book is included in the scripts
+    directory of the package."""
