Nonparametric data segmentation in multivariate time series via joint characteristic functions

ET McGonigle, H Cho - arxiv preprint arxiv:2305.07581, 2023 - arxiv.org
Modern time series data often exhibit complex dependence and structural changes which
are not easily characterised by shifts in the mean or model parameters. We propose a …

Estimation and Inference for Change Points in Functional Regression Time Series

S Kumar, H Xu, H Cho, D Wang - arxiv preprint arxiv:2405.05459, 2024 - arxiv.org
In this paper, we study the estimation and inference of change points under a functional
linear regression model with changes in the slope function. We present a novel Functional …
