Incorporating Model Uncertainty into the Sequential Importance Sampling Framework using a Model Averaging Approach, or Trans-Dimensional Sequential Importance Sampling.
(CREEM, University of St Andrews, 2007) - ReportA sequential Bayesian Monte Carlo approach is proposed in which model space can be explored during the Sequential Importance Sampling (SIS, a.k.a. Particle Filtering) fitting process. The algorithm allows model space to ... -
Accommodating availability bias on line transect surveys using hidden Markov models.
(CREEM, University of St Andrews, 2007) - ReportMaximum likelihood methods are developed which accommodate intermittent animal availability of animals on line transect surveys. Existing 'availability bias' correction methods are shown to be inadequate in general. The ... -
Investigation of towed hydrophone monitoring power for harbour porpoise on the SCANS II survey.
(CREEM, University of St Andrews, 2007) - ReportWe investigate the power of harbour porpoise monitoring programmes which use an index of relative abundance to detect change. Power depends on the variability in the constant of proportionality relating the index to absolute ... -
Methods for estimating sperm whale abundance from passive acoustic line transect surveys.
(CREEM, University of St Andrews, 2007) - Report -
Point and interval estimates of abundance using multiple covariate distance sampling: an example using great bustards.
(CREEM, University of St Andrews, 2007) - ReportDescription of computations to produce sex-specific estimates of density from a multiple-covariate distance sampling analysis. Program Distance 5.0 has limited capacity to bootstrap certain types of analytical situations ...
