%description
Contains functions to compute p-values for the one-sample and two-sample
Kolmogorov-Smirnov (KS) tests and the two-sample Kuiper test for any fixed
critical level and arbitrary (possibly very large) sample sizes. For the
one-sample KS test, this package implements a novel, accurate and
efficient method named Exact-KS-FFT, which allows the pre-specified
cumulative distribution function under the null hypothesis to be
continuous, purely discrete or mixed. In the two-sample case, it is
assumed that both samples come from an unspecified (unknown) continuous,
purely discrete or mixed distribution, i.e. ties (repeated observations)
are allowed, and exact p-values of the KS and the Kuiper tests are
computed. Note, the two-sample Kuiper test is often used when data samples
are on the line or on the circle (circular data). To cite this package in
