DESCRIPTION:The study of the human microbiome involves the integration and
  estimation of trees and networks from  16S rRNA read counts. I will show 
 several examples of double embedding where we use trees and networks  and 
 covariates of interest to establish associations between microbial communi
 ties and  preterm birth\, resilience to antibiotic treatment and batch eff
 ects.  We enrich the standard ecological toolbox of ordination methods usi
 ng generalized singular value decomposition  with weights built from graph
 s and test the effect of covariates using generalizations of the Friedman-
 Rafsky  tests.  &nbsp\;  This talk contains joint work with Elizabeth Purd
 om\, Joey McMurdie\, Julia Fukuyama\, Kris Sankaran and Lan Nguyen.
