Calculate the odds ratio

Description

Calculate the (diagnostic) odds ratio from true positives, false positives, true negatives and false negatives. The inputs must be vectors of equal length.

odds_ratio = (tp / fp) / (fn / tn)

Usage

odds_ratio(tp, fp, tn, fn, ...)

Arguments

tp	(numeric) number of true positives.
fp	(numeric) number of false positives.
tn	(numeric) number of true negatives.
fn	(numeric) number of false negatives.
...	for capturing additional arguments passed by method.
