Websion functions routinely report standard errors that are robust to misspecification of the models that are being estimated. Muller (¨ 2013) gave the corresponding confidence intervals a Bayesian interpretation. A key feature of the approach devel-oped by Eicker, Huber, and White (EHW from hereon), is that WebApr 10, 2016 · We can correct the standard errors for the parameter estimates by using a (Godambe-Eicker-Huber-)White sandwich covariance estimate which corrects for dispersion and heteroscedasticity. Specific to statsmodels: variance weights are not implemented yet (but will be soon)
Webspillover, one should adjust standard errors for spatial correlation, for instance, by reporting the SHAC standard errors. However, there are a few exceptions. When we independently sample a negligible portion of the population, the Eicker-Huber-White (EHW) standard errors would suffice irrespective of the existence of spatial correlation.
