Abstract:
Despite a rapidly-improving accessibility of sequencing resources in microbiome research, amplicon sequencing, especially of the 16S rRNA marker gene, remains the first and most-common metagenomics method applied to new biospecimens. A pervasive misunderstanding of amplicon sequencing data in the microbiome literature is that (1) the sequences must be processed through an ad hoc "OTU" clustering,...

Abstract:
Abstract: The reform program for the over-the-counter (OTC) derivatives market launched by the G-20 nations in 2009 seeks to reduce systemic risk from OTC derivatives. The reforms require that standardized OTC derivatives be cleared through central counterparties (CCPs), and they set higher capital and margin requirements for non-centrally cleared derivatives.

Abstract:
Independent sets in hypergraphs can be encoded as 0-1 configurations on the set of vertices such that each hyperedge is adjacent to at least one 0. This model has been studied in the CS community for its large gap between efficient MCMC algorithms (previously d O(2^{k/2}) ), where d is the largest degree of vertices and k is the minimum size of hyperedges. In this talk we provide a percolation...

Abstract:
Abstract: Covariate balance is crucial for unconfounded descriptive or causal comparisons. However, lack of balance is common in observational studies. This article considers weighting strategies for balancing covariates. We define a general class of weights---the balancing weights---that balance the weighted distributions of the covariates between treatment groups. These weights incorporate the...

Abstract:
Measuring and mapping the global diversity of bacteria and archaea remains a major challenge in microbiology. Maps of the diversity of microbes would aid in understanding the evolutionary and ecological processes underlying global microbial systems, assist forensics and forecasting climate change, and improve agriculture and public health. Despite their utility, constructing maps of microbial...

Statistics at UC Berkeley: We are a community engaged in research and education in probability and statistics. In addition to developing fundamental theory and methodology, we are actively involved in statistical problems that arise in such diverse fields as molecular biology, geophysics, astronomy, AIDS research, neurophysiology, sociology, political science, education, demography, and the U.S. Census. We have forged strong interdisciplinary links with other departments and areas of study, particularly biostatistics, mathematics, computer science, and biology, and actively seek to recruit graduate students and faculty who can help to build and maintain such links. We also offer a statistical consulting service each semester.
