Validating metabarcoding-based biodiversity assessments with multi-species occupancy models: A case study using coastal marine eDNA

Bernoulli variable: ak � BernoulliðOÞ O � Uniformð0; 1Þ An upper limit to species richness (M) is specified a priori and considered large enough when the estimate of true species richness is sufficiently lower than M (i.e., the value of M is in the right tail of the posterior distribution of species richness; [31]). For species k (k = 1,2,. . .M), ak = 1 if species Fig 1.
