calcg: Calculate detection probability for given SE and CP...

In ddalthorp/GenEst: Generalized Mortality Estimator

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.

Usage

calcg(days, param_SE, param_CP, dist)

Arguments

days	Search schedule (vector of days searched)
param_SE	numeric array of searcher efficiency parameters (p and k); must have the name number of rows as the param_CP.
param_CP	numeric array of carcass persistence parameters (a and b) must have the name number of rows as the param_SE.
dist	distribution for the CP model

Value

a vector of detection probabilities for each
