Statistics::Contingency is a Perl module to calculate precision, recall, F1, accuracy, etc. SYNOPSIS use Statistics::Contingency; my $s = new Statistics::Contingency(categories => @all_categories); while (...something...) { ... $s->add_result($assigned_categories, $correct_categories); } print "Micro F1: ", $s->micro_F1, "n"; # Access a single statistic print $s->stats_table; # Show several stats in table form The Statistics::Contingency class helps you calculate several useful statistical measures based on 2x2 "contingency tables". I use these measures to 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..
