论测量平差中的协因数计算

Research on the Association Factor Calculation of Surveying Adjustment

从概率统计学的观点来看，观测量是一个随机变量，描述两个随机变量之间相关性的是协方差，方差、协方差是随机变量的主要统计性质。而方差和协因数有紧密联系，该文着重讨论协因数的统一变量简明计算及协因数的求逆方法。

The concept of measurement is a random variable from the probability and Statistics point of view, describing the correlation between two random variables are ofcovariance, covariance is the main statistical properties of random variables. While the covariance and association factor are closely linked, this article focuses on concise calculation of the unity of the variable and inverse methods of association factor.
