Estimating Partial Group Delay
提出了一种估计多通道时间序列中两通道间偏群延迟的方法，并给出了估计序列一致性和渐近正态性的条件。
The partial group delay between two channels of a multiple time series has an interpretation as the time lag between frequency components of the two channels after adjustments have been made for the influence of the remaining channels. A procedure for estimating partial group delay is proposed, and conditions for consistency and asymptotic normality of the estimating sequence are obtained.
