estN: Estimating population size via sample coverage

Description

Population size estimation based on sample coverage approach for closed capture-recapture models.

Usage

1
estN(z, method="Indep", se=FALSE, nboot=200)

Arguments

z

the vector of capture histories or ascertainment records.

method

the method employed to estimate population size. method="Indep": population size estimate for independent samples;
method="HSC": population size estimate for sufficiently high sample coverage cases;
method="LSC": one-step population size estimate for low sample coverage cases.

se

should calculus bootstrap standard error?

nboot

the number of bootstrap resampling times.

Value

population size estimator
