Testing for functional white noise in high dimensions
Jinyuan Chang, Qing Jiang, Xinghao Qiao +1
White noise testing is a fundamental problem in time series analysis. Yet it remains largely unsolved for high-dimensional functional time series, despite the growing attention thi…

Time Series Gaussian Chain Graph Models
Qin Fang, Xinghao Qiao, Zihan Wang
Time series graphical models have recently received considerable attention for characterizing (conditional) dependence structures in multivariate time series. In many applications,…

On the modelling and prediction of high-dimensional functional time series
Jinyuan Chang, Qin Fang, Xinghao Qiao +1
We propose a two-step procedure to model and predict high-dimensional functional time series, where the number of function-valued time series is large in relation to the length…
