WebSep 11, 2024 · $\begingroup$ @FrankHarrell, I forgot to mention that I am working in the rare setting (MAF < 0.1%), with thousands of hypotheses (i.e. 2x2 tables) so it is quite likely I will get expected cell counts exactly zero. It is also my experience from simulations that the $\chi^2$ statistic is too liberal and does not always control the FDR (i.e. inflation).
