While variances are harder to estimate than means, it is even harder to estimate correlations and to make inferences on them. We consider frequentist and Bayesian approaches for a problem where knowing the correlation between two component responses in a system is important in determining separate production requirements for the two components.

评估相关性以评估两个组件系统的性能及其对指定单独生产需求的影响

虽然方差比均值更难估计，但更难估计相关性并对其进行推断。我们考虑问题的常问和贝叶斯方法，其中了解系统中两个组件响应之间的相关性对于确定两个组件的单独生产要求非常重要。
