多变量时间序列的贝叶斯预测:可扩展性、结构不确定性和决策

Bayesian forecasting of multivariate time series: Scalability, structure uncertainty and decisions

Mike West

摘要:

综述了多元时间序列贝叶斯状态空间建模的研究进展。一个主要的重点是解耦/重新耦合的概念,使应用程序的状态空间模型越来越大规模的数据,适用于连续或离散的时间序列的结果。其范围包括经济和金融等领域的预测和多元波动分析的大规模动态图形模型,商业销售和需求预测等领域的离散/计数时间序列预测的多尺度方法,以及互联网流量监控等领域的动态网络流量模型。在应用中,明确的预测,监测和决策目标是至关重要的,并应考虑到模型评估和比较,这是一个突出的观点。

英文摘要:

I overview recent research advances in Bayesian state-space modeling of multivariate time series. A main focus is on the decouple/recouple concept that enables application of state-space models to increasingly large-scale data, applying to continuous or discrete time series outcomes. The scope includes large-scale dynamic graphical models for forecasting and multivariate volatility analysis in areas such as economics and finance, multi-scale approaches for forecasting discrete/count time series in areas such as commercial sales and demand forecasting, and dynamic network flow models for areas including internet traffic monitoring. In applications, explicit forecasting, monitoring and decision goals are paramount and should factor into model assessment and comparison, a perspective that is highlighted.
