A stochastic method to estimate a zero-inflated two-part mixed model for human microbiome data
John Barrera, Cristian Meza, Ana Arribas-Gil
Human microbiome studies based on genetic sequencing techniques produce compositional longitudinal data of the relative abundances of microbial taxa over time, allowing to understa…
