Cluster-robust variance estimation


James E. Pustejovsky

R and Stata packages for calculating cluster-robust variance estimators (i.e., sandwich estimators) with small-sample corrections, including the bias-reduced linearization estimator of Bell and McCaffrey (2002) and extensions proposed in Tipton (2015), Tipton and Pustejovsky (2015), and Pustejovsky and Tipton (2016).
