高维张量时间序列的因子模型

Factor Models for High-Dimensional Tensor Time Series

Rong Chen, Dan Yang, Cun-hui Zhang

摘要:

由于现代数据收集能力,现在在广泛的应用中常规地收集大型张量(多维阵列)数据。这些观测通常是随时间进行的,形成张量时间序列。本文提出了一种分析高维动态张量时间序列和多类动态运输网络的因子模型方法。两个估计程序,以及它们的理论性质和仿真结果。两个应用程序被用来说明模型和它的解释。

英文摘要:

Large tensor (multi-dimensional array) data are now routinely collected in a wide range of applications, due to modern data collection capabilities. Often such observations are taken over time, forming tensor time series. In this paper we present a factor model approach for analyzing high-dimensional dynamic tensor time series and multi-category dynamic transport networks. Two estimation procedures along with their theoretical properties and simulation results are presented. Two applications are used to illustrate the model and its interpretations.
