WebbThe sensitivity and specificity are 29/33=88% and 38/44=86%. In this instance FPR and FNR are both very close to each other. When this is the case, they will also be very close to MR. In fact one can show that MR is a weighted average of FPR and FNR: MR = w*FPR + (1-w)*FNR and the weight (w) is the proportion of nights with an observed frost.
