Regime change detection is concerned with identifying abnormal system behaviors and abrupt changes from one regime to another. This paper proposes a novel method capable of detecting regime change points in sequential time series. Our approach is based on a sensitivity study of a global model combining, with a multiplicative effect, the local models describing the different modes of functioning.
