sePetersen: Standard Error of the Petersen Estimator

Description

Calculates the standard error of the Petersen estimator in a mark-recapture experiment, with given values of sample sizes and number of recaptures.

Usage

sePetersen(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 sqrt((n1^2)*n2*(n2-m2)/(m2^3))
