Example of data formatting for estimating the infection prevalence of a pathogen at a single site of interest using occupancy models. Each row corresponds to a sampled individual and the values within a row correspond to the results from three samples collected. Samples where the pathogen was detected are coded as a “1″ while nondetections are coded as a “0.” Species identity and tissue sample type can also be included as covariates, but are not shown here for simplicity.
