Causal Mediation Analysis for Zero-inflated Mixture Mediators
Meilin Jiang, Seonjoo Lee, A. James O'Malley +2
Causal mediation analysis is an important statistical tool to quantify effects transmitted by intermediate variables from a cause to an outcome. There is a gap in mediation analysi…
IFAA: Robust association identification and Inference For Absolute Abundance in microbiome analyses
Zhigang Li, Lu Tian, A. James O'Malley +8
The target of inference in microbiome analyses is usually relative abundance (RA) because RA in a sample (e.g., stool) can be considered as an approximation of RA in an entire ecos…
MarZIC: A Marginal mediation model for Zero-Inflated Compositional mediators with applications to microbiome data
Quran Wu, A. James O'Malley, Janaka S. S. Liyanage +9
The human microbiome can contribute to pathogeneses of many complex diseases by mediating disease-leading causal pathways. However, standard mediation analysis methods are not adeq…
Conditional regression based on a multivariate zero-inflated logistic normal model for microbiome relative abundance data
Zhigang Li, Katherine Lee, Margaret R. Karagas +4
The human microbiome plays critical roles in human health and has been linked to many diseases. While advanced sequencing technologies can characterize the composition of the micro…
