Propensity score modeling strategies for the causal analysis of observational data
Biostatistics - Tập 3 Số 2 - Trang 179-193 - 2002
Katherine Huppler Hullsiek, Thomas A. Louis
Zero-inflated generalized Dirichlet multinomial regression model for microbiome compositional data analysis
Biostatistics - Tập 20 Số 4 - Trang 698-713 - 2019
Zheng-Zheng Tang, Guanhua Chen
SummaryThere is heightened interest in using high-throughput sequencing technologies to quantify abundances of microbial taxa and linking the abundance to human diseases and traits. Proper modeling of multivariate taxon counts is essential to the power of detecting this association. Existing models are limited in handling excessive zero observations in taxon counts...... hiện toàn bộ

Latent variable modeling for the microbiome
Biostatistics - Tập 20 Số 4 - Trang 599-614 - 2019
Kris Sankaran, Susan Holmes
SummaryThe human microbiome is a complex ecological system, and describing its structure and function under different environmental conditions is important from both basic scientific and medical perspectives. Viewed through a biostatistical lens, many microbiome analysis goals can be formulated as latent variable modeling problems. However, although probabilistic l...... hiện toàn bộ
Sparse inverse covariance estimation with the graphical lasso
Biostatistics - Tập 9 Số 3 - Trang 432-441 - 2008
Jerome H. Friedman, Trevor Hastie, Robert Tibshirani
Abstract We consider the problem of estimating sparse graphs by a lasso penalty applied to the inverse covariance matrix. Using a coordinate descent procedure for the lasso, we develop a simple algorithm—the graphical lasso—that is remarkably fast: It solves a 1000-node problem (∼500000 parameters) in at most a minute and is 30–4000 times faster than...... hiện toàn bộ
