design effect

设计效应：在调查方法学中，设计效应（通常表示为Deff或Deft2）是对采样设计对估计量方差的预期影响的度量。它被计算为基于（通常是）复杂采样设计的样本的估计量的方差与基于相同数量元素的简单随机样本（SRS）的替代估计量的方差的比值。Deff（无论是估计还是已知的先验）可用于调整估计量的方差，以适应非简单随机抽样的情况。它还可以用于样本量计算和量化样本的代表性。术语“设计效应”由Leslie Kish于1965年创造。

The adjustment inflates the variance of parameter estimates, and therefore their standard errors, which is necessary to allow for correlations among clusters of observations.
