Model formulation

Model formulation in JAGS (Generalized Linear Mixed Model (GLMM) with zero-inflation)

R scripts

R-functions needed to apply the model to data. Example in R on how to use the model.

Gene count data used in the study

Human gut I (from Qin et al 2010)
Human gut II (from Qin et al 2012)
