risk_ratio | R Documentation |
Calculate the risk ratio (or relative risk) from
true positives, false positives, true negatives and false negatives.
The inputs must be vectors of equal length.
risk_ratio = (tp / (tp + fn)) / (fp / (fp + tn))
risk_ratio(tp, fp, tn, fn, ...)
tp |
(numeric) number of true positives. |
fp |
(numeric) number of false positives. |
tn |
(numeric) number of true negatives. |
fn |
(numeric) number of false negatives. |
