Statistical library package to calculate the Loglikelihood ratio for trigrams. This package should be used with statistic.pl and rank.pl.
The log-likelihood ratio measures the devitation between the observed data and what would be expected if <word1>, <word2>, and <word3> were independent. The higher the score, the less evidence there is in favor of concluding that the words are independent.
