| calcg {GenEst} | R Documentation |
Calculate detection probability for given SE and CP parameters and search schedule.
Description
Calculate detection probability (g) given SE and CP parameters and a search schedule.
The g given by calcg is a generic aggregate detection
probability and represents the probability of detecting a carcass that
arrives at a (uniform) random time during the time spanned by the search
schedule for the the given SE and CP parameters. This differs from the GenEst
estimation of g when the purpose is to estimate total mortality (M), in
which case the detection probability varies with carcass arrival interval
and is difficult to summarize statistically. calcg provides a
useful "big picture" summary of detection probability, but would be
difficult to work with for estimating M with precision.
