In small … 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.

WebSecond, we show that the standard Eicker-Huber-White (EHW) variance estimator remains conservative when we take into account design-based uncertainty. Third, we show that there is a simple finite-population correction to the EHW variance estimator for descriptive estimands but not for causal estimands.
