The Statistics::Contingency class helps you calculate several useful
|
||
|
statistical measures based on 2x2 "contingency tables". These can be
|
||
|
used for 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.
