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…

Autoregressive networks with dependent edges

Jinyuan Chang, Qin Fang, Eric D. Kolaczyk +2

We propose an autoregressive framework for modelling dynamic networks with dependent edges. It encompasses models that accommodate, for example, transitivity, degree heterogenenity…
