The S-lang statistics module contains a number of well-known statistical tests and functions for the statistical analysis of data. Wherever possible routines that compute the exact ``p-values'' have been implemented, e.g., for the Kolmogorov-Smirnov tests.
It is assumed that the user of the module is familiar with statistics and significance-testing. This document describes how to use the module and makes no attempt to describe the inherent strengths or weaknesses of the statistical tests implemented by the module. The user is referred to the statistical literature for information about the latter.
