InspectChangepoint: High-Dimensional Changepoint Estimation via Sparse Projection

Provides a data-driven projection-based method for estimating changepoints in high-dimensional time series. Multiple changepoints are estimated using a (wild) binary segmentation scheme.

Authors:Tengyao Wang, Bertille Follain and Richard Samworth
