prtEvalPdAtPf

prtEvalPdAtPf Returns the probability of false alarm at a desired probability of detection on the receiver operating curve. PD = prtEvalPdAtPf(prtClassifier, prtDataSet, pfDesired) returns the probabilty of detection PD. prtDataSet must be a labeled, binary prtDataSetStandard object. prtClassifier must be a prtClass object. pfDesired is the desired probability of false alarm and must be between 0 and 1. pfDesired = prtEvalPdAtPf(prtClassifier, prtDataSet, pfDesired, nFolds) returns the probabilty of false alarm pfDesired on the receiver operating curve with K-fold cross-validation. prtDataSet must be a labeled, binary prtDataSetStandard object. prtClassifier must be a prtClass object. pfDesired is the desired probability of detection and must be between 0 and 1. nFolds is the number of folds in the K-fold cross-validation. pfDesired = prtEvalPdAtPf(prtClassifier, prtDataSet, pfDesired, xValInds) same as above, but use crossValidation with specified indices instead of random folds. Example: dataSet = prtDataGenSpiral; classifier = prtClassDlrt; pf = prtEvalPdAtPf(classifier, dataSet,.01)
