Abstract(in English) | Detecting changes of the average structures in a multi-dimensional sequence is an important task in various fields. In this problem, since change-points can be observed in a part of the dimensions, it is also necessary to detect the dimensions of change as well as the time points of change. Furthermore, in order to make statistical inferences on the detected change points, it is necessary to take into account the selection bias owing to the algorithm. In this study, we perform multi-dimensional change point detection using the scan statistic and propose a valid statistical inference method for the detected change points using the framework of conditional selective inference. |
