Conditional Spectral Analysis of Replicated Multiple Time Series With Application to Nocturnal Physiology
重复观测多元时间序列的条件谱分析:夜间生理应用
This article considers the problem of analyzing associations between power spectra of multiple time series and cross-sectional outcomes when data are observed from multiple subjects. The motivating application comes from sleep medicine, where researchers are able to non-invasively record physiological time series signals during sleep. The frequency patterns of these signals, which can be quantified through the power spectrum, contain interpretable information about…
