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.") + (license (list license:gpl2+ license:gpl3+)))) + (define-public r-lambda-r (package (name "r-lambda-r") |
