Smoothness prior approach to explore mean structure in large-scale time series

摘要

This article is addressed to the problem of modeling and exploring mean value structure of large-scale time series data and time-space data. A smoothness prior modeling approach (Smoothness Prior Analysis of Time Series, Lecture Notes in Statistics, vol. 116, Springer, New York, 1996.) is taken. In this approach, the observed series are decomposed into several components each of which are expressed by smoothness priors models. In the analysis of P05 and GPS data, various useful information were extracted by this decomposition, and result in discoveries in these areas.
