(synopsis "Goodness-of-Fit test for multinomial data")
(description
"This package provides an exact Goodness-of-Fit test for
multinomial data with fixed probabilities. It can be used to
determine whether a set of counts fits a given expected ratio. To see
whether a set of observed counts fits an expectation, one can examine
all possible outcomes with @code{xmulti()} or a random sample of them
with @code{xmonte()} and find the probability of an observation
deviating from the expectation by at least as much as the observed.
As a measure of deviation from the expected, one can use the
log-likelihood ratio, the multinomial probability, or the classic
chi-square statistic. A histogram of the test statistic can also be
plotted and compared with the asymptotic curve.")
