The clustering test's null hypothesis is misspecified

forThis argument, if it holds, bears in favour of the claim.constitution →A spatial statistical test does not validly establish non-random clustering of early COVID-19 cases around the Huanan Market

The argument

Because linked claim, the test measures only departure from a population-proportional, non-contagious expectation that almost any central Wuhan landmark would also reject; rejecting such a null therefore does not isolate clustering specific to the market, so the test does not validly establish non-random clustering around it.

Does it work?

The inference goes through granting its premise: if the test only measures departure from a population-proportional, non-contagious expectation that any central landmark would also reject, then rejecting that null does not isolate clustering specific to the market. Everything turns on the population-density null being statistically inappropriate, which is contested. The caveat is the robustness rebuttal: the original authors report the clustering also survives a social-media-mobility baseline, which, if sound, blunts the misspecification objection, but that rebuttal is itself disputed. The argument thus remains a serious but unsettled line against the claim's negation.
