Precision


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

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