%X The state of classifier incongruence in decision making systems incorporating multiple classifiers is often
an indicator of anomaly caused by an unexpected observation or an unusual situation. Its assessment is
important as one of the key mechanisms for domain anomaly detection. In this paper, we investigate the
sensitivity of Delta divergence, a novel measure of classifier incongruence, to estimation errors. Statistical properties of Delta divergence are analysed both theoretically and experimentally. The results of the
analysis provide guidelines on the selection of threshold for classifier incongruence detection based on
this measure.
