SACAT: Structural-Absence and Conditional-Abundance Testing

Provides depth-aware taxon-level inference for microbiome count data. SACAT separates group differences in structural-absence probability from differences in mean log relative abundance among samples in which a taxon is present. It accounts for finite-depth nondetection, centers abundance effects against a target-excluded cross-taxon reference, reports component-specific and omnibus tests, and visualizes statistical evidence, observed detection, estimated zero sources, and abundance distributions.
