论文摘要
我们通过提供足够的条件来计算两个随机变量的协方差来扩展路径分析。这是通过纠正某些部分差异比率的乘积来纠正协方差来完成的。结果,部分协方差保留了协方差的显着特征,即在感兴趣的两个变量之间的路径上分解边缘。
We extend path analysis by giving sufficient conditions for computing the partial covariance of two random variables from their covariance. This is specifically done by correcting the covariance with the product of some partial variance ratios. As a result, the partial covariance retains the covariance's salient feature of factorizing over the edges in the paths between the two variables of interest.
