FNRate


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

The array property FNRate returns the false negative rate for binary response variables, assuming that the binary target values are 1 and "not 1" (usually 0 or -1). FNRate is automatically reset to its default value (-1.0) when the size of the test set is changed or if the cross validation is aborted (see OnCheckAbort event).

The parameter varix specifies the index of the response variable and may assume values between 1 and YMat.NrOfColumns.

Hint: If the (negative) target value of a particular output variable is not equal to 0.0 the FNRate will be invalid because the false negative rate is defined only for binary classifiers assuming that a negatively identified observation is indicated by a response value of 0.0
