mads-package: Multi-Analysis Distance Sampling (mads)

Description Details Author(s)

Description

Can perform distance sampling analyses on a number of species at once and can account for unidentified sightings. Unidentified sightings refer to sightings which cannot be allocated to a single species but may instead be allocated to a group of species. The abundance of each unidentified group is estimated and then prorated to the species estimates. The multi-analysis engine can also incorporate model and covariate uncertainty. Variance estimation is via a non parametric bootstrap. The methods implemented are described in Gerodette T. and Forcada J. (2005) <10.3354/meps291001> "Non-recovery of two spotted and spinner dolphin populations in the eastern tropical Pacific Ocean".

Details

The main function in this package is execute.multi.analysis.

Further information on distance sampling methods and example code is available at http://distancesampling.org/R/.

We are also in the process of setting up a new area of the website for vignettes / example code at http://examples.distancesampling.org.

For help with distance sampling and this package, there is a Google Group https://groups.google.com/forum/#!forum/distance-sampling.
