precisely stated assumptions about moments and cluster sizes. We then propose several wild bootstrap procedures and prove that … they are asymptotically valid. Simulations suggest that bootstrap inference tends to be much more accurate than inference … that bootstrap inferences can differ substantially from conventional ones. …
