There are racial disparities in the COVID-19 test positivity rate, suggesting\nthat minorities may be under-tested. Here, drawing on the literature on\nstatistically assessing racial disparities in policing, we 1) illuminate a\nstatistical flaw, known as infra-marginality, in using the positivity rate as a\nmetric for assessing racial disparities in under-testing; 2) develop a new type\nof Bayesian threshold test to measure disparities in COVID-19 testing and 3)\napply the test to measure racial disparities in testing thresholds in a\nreal-world COVID-19 dataset.\n
