vPetersen: Estimated Variance of the Petersen Estimator
Description
Calculates the estimated variance of the Petersen estimator in a
mark-recapture experiment, with given values of sample sizes and number of
recaptures.
Usage
vPetersen(n1, n2, m2)
Arguments
n1
Number of individuals captured and marked in the first sample. This
may be a single number or vector of values.
n2
Number of individuals captured in the second sample. This may be a
single number or vector of values.
m2
Number of marked individuals recaptured in the second sample. This
may be a single number or vector of values.
Value
The estimate variance of the Petersen estimator, calculated as
(n1^2)*n2*(n2-m2)/(m2^3)
