+Cramer's V, odds ratio, R-squared, quantiles (including median), proportions,
+different types of correlation measures, difference in means, quantiles and
+medians.  Many of the classic confidence intervals are described in Smithson,
+M. (2003, ISBN: 978-0761924999).  Bootstrap confidence intervals are
+calculated with the R package @code{boot}.  Both one- and two-sided intervals
+are supported.")
