Table 2 Root mean squared error of posterior means (RMSE), precision of full posterior (Prec; smaller is better), and credible interval coverage (Cov) for localization of ut from 100 simulated data sets analyzed using the independent localization model (Ind loc) and three forms of movement-assisted localization: (Mvmt DO) detection occasions only, (Mvmt KI) assuming the signal interval is known, or (Mvmt UI) modeling the unknown signal interval as a random variable. Values are presented as a function of the number of receivers where the signal was detected. Only the known-interval model localizes to a specific ut when 0 detections. Due to their rarity, results for signals detected at 7 or 8 receivers were excluded from results
From: Movement-assisted localization from acoustic telemetry data
