Multi-Analysis Distance Sampling

Performs distance sampling analyses on a number of species accounting for unidentified sightings, model uncertainty and covariate uncertainty.

mads 0.1.5

Bug Fixes

  • Fixed bug in the call to repeat fitting of the detection functions by ddf in mrds. Previously, information such as whether the data were point transect, binned, left-truncated etc. was lost from the ddf object and may have caused dht to produce incorrect estimates of abundance / density. The default options of line transects with exact distances will not have been affected.

mads 0.1.4

Notes

  • Bug fix for warnings
  • Catches the case when fitted values in ddf are 0
  • Updated package structure

mads 0.1.3

Notes

  • See notes from version 0.1.1

New Features

  • The user may now specify which field gives the species code rather than it being fixed as 'species'

mads 0.1.2

Notes

  • See notes from version 0.1.1

New Features

  • Improved system of warning messages compatible with Distance 7

mads 0.1.1

Notes

  • These methods were designs to replicate the analyses of those in Gerrodette and Forcada (2005) Currently we are still in the testing phase to ensure the methods in mads match those of Gerrodette and Forcada Our pro-rating methods for individuals are the same, but in addition we also pro-rate clusters. We do not perform model averaging only model selection at each iteration. There may be small differences in how covariate uncertainty is incorporated.
