$ℓ^{2}$ Inference for Change Points in High-Dimensional Time Series via a Two-Way MOSUM

Jiaqi Li, Likai Chen, Weining Wang +1

We propose an inference method for detecting multiple change points in high-dimensional time series, targeting dense or spatially clustered signals. Our method aggregates moving su…
