module to calculate precision, recall, F1, accuracy, etc.

The Statistics::Contingency class helps you calculate several useful statistical measures based on 2x2 "contingency tables". These measures can help judge the results of automatic text categorization experiments, but they are useful in other situations as well.

The general usage flow is to tally a whole bunch of results in the Statistics::Contingency object, then query that object to obtain the measures you are interested in. When all results have been collected, you can get a report on accuracy, precision, recall, F1, and so on, with both macro-averaging and micro-averaging over categories.
