This paper presents a unified mathematical derivation of the asymptotic behaviour of the three main forms of partial directed coherence (PDC). Numerical examples are used to contrast PDC, gPDC (generalized PDC) and iPDC (information PDC) as to meaning and applicability and, more importantly, to show their essential statistical equivalence insofar as connectivity inference is concerned.
本文提出了一种统一的数学推导，用于研究三种主要形式的偏定向相干（PDC）的渐近行为。通过数值示例对比了 PDC、gPDC（广义 PDC）和 iPDC（信息 PDC）的意义和适用性，更重要的是，从连通性推断的角度展示了它们在本质上的统计等价性。
