摘要
The aim of this paper is to present two on-line, sliding window segmentation algorithms. Detection nonstationarity is based on parameter fluctuations and change point localization of the Akaike information criterion. Asymptotic properties of the proposed algorithms are analyzed. Specifically, the limiting distributions are derived and the asymptotic threshold values are tabulated for future reference. Finite sample simulations are performed to illustrate the usefulness of these algorithms.
