SYNOPSIS

Statistical library package to calculate the Loglikelihood ratio. This package should be used with statistic.pl and rank.pl.

DESCRIPTION

The log-likelihood ratio measures the devitation between the observed data and what would be expected if <word1> and <word2> were independent. The higher the score, the less evidence there is in favor of concluding that the words are independent.
