Accuracy


Unit: SDL_statis
Class: TCrossValidator
Declaration: property Accuracy [varix: integer]: double;

The array property Accuracy returns the accuracy for binary response variables, assuming that the binary target values are 1 and "not 1" (usually 0 or -1). The parameter varix specifies the index of the response variable and may assume values between 1 and YMat.NrOfColumns.

Hint: If the (positive) target value of a particular output variable is not equal to 1.0 the Accuracy will be invalid because the true positive rate is defined only for binary classifiers assuming that a positively identified observation is indicated by a response value of 1.0
