Online Jump and Kink Detection in Segmented Linear Regression: Statistical Optimality Meets Computational Efficiency

open access: yesJournal of Time Series Analysis, EarlyView.
ABSTRACT We consider the problem of sequential (online) estimation of a single change point in a piecewise linear regression model under a Gaussian setup. We demonstrate that certain CUSUM‐type statistics attain the minimax optimal rates for localizing the change point.

Our organising framework clarifies why neglecting the cross‐sectional and longitudinal structure of these data leads to hard‐to‐detect data leakage, inflated out‐of‐sample performance, and an inadvertent overestimation of the real ...
