Empirical power. Empirical power was evaluated in all simulation settings, using a sample size of n=100 and 25% censoring. K w, K u, K BC, and K 0.5 represent results for the weighted UniFrac kernel, unweighted UniFrac kernel, Bray-Curtis kernel, and generalized UniFrac kernel with α=0.5, respectively. γ is the true effect size for the associated cluster or OTUs. a Setting 1; survival is associated with OTU counts in a common cluster containing 19.7% of all reads. b Setting 3; survival is associated with the presence or absence of each taxon in a common cluster. c Setting 1; survival is associated with OTU counts in a rare cluster containing 0.9% of all reads. d Setting 3; survival is associated with the presence or absence of each taxon in a rare cluster. e Setting 2; survival is associated with the ten most common OTUs, regardless of cluster membership. f Setting 4; survival is associated with 40 OTUs selected at random, regardless of cluster membership
