| dc.description | Balancing a rare and serious possibility against a more common and less serious one is a familiar problem in many situations, such as the prediction of rare diseases. The relative costs of forecasting errors can be used for any prediction method that gives an estimated probability of a future event. The probability at which the likely cost (defined as cost x probability) of a possible false negative is exactly equal to that of a possible false positive gives the relevant cutpoint and all subjects with probability of disease greater than this have a positive test result. All standard methods of logistic regression will give the log-odds and hence the predicted probability of a positive outcome for every subject: | |
