On The So-Called “Huber Sandwich Estimator” and “Robust ...
www.stat.berkeley.eduOn The So-Called “Huber Sandwich Estimator” and “Robust Standard Errors” by David A. Freedman Abstract The “Huber Sandwich Estimator” can be used to estimate the variance of the MLE when the underlying model is incorrect. If the model is nearly correct, so are the usual standard errors, and robustification is unlikely to help much.
A Practitioner’s Guide to Cluster-Robust Inference
cameron.econ.ucdavis.eduSection V considers clustering when there is more than one way to do so and these ways are not nested in each other. Section VI considers how to adjust inference when there are just a few clusters as, without adjustment, test statistics based on the cluster-robust standard errors over-reject and confidence intervals are too narrow. Section VII
Useful Stata Commands 2019 - Rensselaer Polytechnic Institute
homepages.rpi.eduMost commands work the same in Stata versions 12, 11, 10, and 9. Throughout, estimation commands specify robust standard errors (Eicker-Huber-White heteroskedastic-consistent standard errors). This does not imply that robust rather than conventional estimates of Var[b|X] should always be used, nor that they are sufficient.
