pcru.bin

matrix of detections for pcru

pcru.data

array of covariates measured at the observation-level for pcru

pfer.y

matrix of observed calling indices for pfer

pfer.bin

matrix of detections for pfer

pfer.data

array of covariates measured at the observation-level for pfer

Details

The rows of pcru.y, pcru.bin, pfer.y, and pfer.bin correspond to sites and columns correspond to visits to each site. The first 2 dimensions of pfer.data and pcru.data are matrices of covariates that correspond to the observation matrices (sites \times observation), with the 3rd dimension corresponding to separate covariates.
