[…] . OMiAT [] is a further adaptive test which approximates to an optimal test adaptively throughout the sum of powered score tests (SPU) [] and MiRKAT tests. By including SPU tests in the search space, OMiAT robustly discovers rare, mid-abundant, and abundant associated lineages along with the functionality of Optimal MiRKAT.There has also been increasing interest in discovering microbial taxa that […]
