Microbiome subject similarity network: A visualization of the 121 node microbiome subject similarity network with nodes colored by the partition using the classic (a.) and attributed (b.) stochastic block model. a. Fitting the classic stochastic block model to the network, 7 communities were identified. b. Fitting the attributed stochastic block model to the network with the attributes being the first 5 principle components of each subject’s OTU count vector (metagenomic profile), 6 communities were identified. Incorporating attributes in inferring this partition removed some of the noise in the partition on the network, specifically in community 3 in (a)
