Three examples from our simulation study are shown in Table 1 . Data are generated from three different sets of parameters (CWS (8) and CBS (r)), and the aim is to detect a shift in mean of 2s.d. Dataset 1 has no CWS and CBS (800 and r 00). Dataset 2 includes CWS (8 00.4), while dataset 3 presents both CWS and CBS (8 00.4 and r00.3). For all datasets, the parallel method gives longer delays compared with other methods. In the case of dataset 1 (no CWS and CBS), the last three methods perform similarly. When CWS is present (dataset 2), the proposed method performs better than the others with slightly lower delay and much lower FAR. This pattern is repeated when CBS is incorporated (dataset 3).
