Clustered standard errors (or Liang-Zeger standard errors) are measurements that estimate the standard error of a regression parameter in settings where observations may be subdivided into smaller-sized groups ("clusters") and where the sampling and/or treatment assignment is correlated within each … Visa mer Clustered standard errors are often useful when treatment is assigned at the level of a cluster instead of at the individual level.

WebbThe three methods that were used to analyze the simulated data sets were: 1) an individual-level linear regression model with Gaussian random intercepts for clusters (estimated via maximum likelihood); 2) an individual-level t -statistic with cluster-robust standard errors to account for clustering, and 3) the generalized estimating equations … Webbour proposals produce standard errors that are substantially larger than the robust standard errors, but also substantially smaller than the conventional version of cluster …
