Example of Sensitivity and specificity For example, Wikipedia provides the following definitions (they seem pretty standard): True positive rate (or sensitivity): T P R = T P / ( T P + F N) False positive rate: F P R = F P / ( F P + T N) True negative rate (or specificity): T N R = T N / ( F P + T N) These are the two kinds of errors in a binary test, in contrast to the two kinds of correct result (a true positive and a true negative). They are also known in medicine as a false positive (or false negative) diagnosis, and in statistical classification as a false positive (or false negative) error. true positive: Statistics A positive test result, that accurately reflects the tested-for activity of an analyte A false positive is the case where the estimated category is too large.
