\title{General Information on the coin Package}
\description{
The \pkg{coin} package implements a general framework for conditional
inference procedures, commonly known as \emph{permutation tests},
theoretically derived by Strasser & Weber (1999). The conditional
expectation and covariance for a broad class of multivariate linear
statistics as well as the corresponding multivariate limiting distribution
was derived by Strasser & Weber (1999). These results are
utilized to construct tests for independence between two sets of variables.
Beside a general implementation of the abstract framework the package offers
a rather huge set of convenience functions implementing well known classical
as well as less prominent classical and non-classical test procedures
in a conditional inference framework. Examples are linear rank statistics for
the two- and K-sample location and scale problem against ordered and
unordered alternatives including post-hoc tests for arbitrary contrasts,
tests of independence for contingency tables, two- and K-sample tests for
censored data, tests for independence of two continuous variables as well as
tests for marginal homogeneity and symmetry. Conditional counterparts of
most of the classical procedures
given in famous text books like Hollander & Wolfe (1999) or Agresti (2002)
can be implemented as part of the general framework without much effort.
Approximations of the exact null distribution via the limiting distribution and
conditional Monte-Carlo procedures are available for every test while the
exact null distribution is currently available for two-sample problems only.
