NDest: Estimates density and abundance.
In DistanceDevelopment/hsltm: Line transect estimation with hidden state availability models
Description
Horvitz-Thompson like estimation of density and abundance of groups and of individuals, as well as
of group size (estimated as the ratio of individual density and group density estimates). Produces
estimates by stratum and over all strata.
Usage
1
NDest(dat, hmltm.fit, W)
Arguments
dat
MRDS data frame. Must have cols "stratum","area","transect","L","size","object","x","y"
(and possibly others).
hmltm.fit
output from fit.hmltm.
W
perpendicular truncation distance for estimation.
