Size of the Wild Population
sit_wild_size.Rd
Estimate the size of the wild population, via the Lincoln Index.
Arguments
- x
A
sit
object.- pool
Logical. Whether to aggregate data from released populations.
- species
a character vector of species to be returned. Defaults to
NULL
, which ignores the species variable.
Details
This provides multiple estimates of the population size, one for each age $t$ and for each released population, which can be averaged to compute a final estimate based on all the available data.
The calculation needs to be split by released population. First, because survival rates could be different among populations, but also because the number $n_t$ of captured wild males at a given date can be compared against the number of captured sterile males $m_t$ at different ages.
