Witryna14 kwi 2024 · This paper proposes a generalization of the local bootstrap for periodogram statistics when weakly stationary time series are contaminated by additive outliers. To achieve robustness, we suggest replacing the classical version of the periodogram with the M-periodogram in the local bootstrap procedure.

In Section 4, we introduce our estimator of the time point u0, which is based on a refinement of the CUSUM principle. To construct it, we proceed in two steps. In the first, we set up a function D:[0,1]→R≥0,whereD(u ...
