ABSTRACT:
With the advent of next-generation sequencing in recent years, scientists are able to
produce large amounts of microbiome and metagenome relative abundance data. 
Statistical methods have been developed to analyze this data. 
However, in some instances, it is not clear which statistical method is appropriate. 
Also, methods are needed for investigating microbiome and metagenome relationships with a host. 
This dissertation describes research focused on three objectives: 1) determine appropriate statistical methods for detecting
differential abundance in microbiome and metagenome datasets, 2) develop tools and techniques for identifying and comparing correlation
networks, and 3) use methods from objectives 1 and 2 to analyze an Ossabaw pig dataset.
