kappa: Cohen's kappa

In EU-ECDC/HerpesZosterModel: ZM

Description

Cohen's kappa (κ), also known as Heidke's skill score, is given by

κ = 1 - (1 - p_o) / (1 - p_e)

where p_o is the observed frequency and p_e is the expected frequency. We calculate p_o and p_e based on true positives (TP), true negatives (NP), false positives (FP), and false negatives (FN).

Usage

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

Arguments

tp	True positives
tn	True negatives
fp	False positives
fn	False negatives
