NegPredValue

Unit: SDL_statis
Class: TCFEvaluator
Declaration: function NegPredValue: double;

The function NegPredValue calculates the negative predictive value of the classifier for a particular threshold which has to be set by calling the method CalcConfusionMatrix. The valid range for the negative predictive value is from 0.0 to 1.0. A negative value indicates a condition where the negative predictive value cannot be calculated:
-1 ... the method CalcConfusionMatrix has not been called before
-2 ... the actual (true) values are not dichotomous
