An estimating function approach to the inference of catch-effort models

摘要: A class of catch-effort models, which allows for heterogeneous removal probabilities, is proposed closed populations. The model includes three types probabilities: multiplicative, Poisson and logistic. usual generalized models then become special cases. equivalence the a type capture-recapture discussed. unified estimating function approach used to estimate initial population size. For homogeneous model, resulting size estimator based on optimal functions asymptotically equivalent maximum likelihood estimator. One advantage our that it can be extended handle populations in estimators do not exist. bootstrap method applied construct variance confidence intervals. We illustrate by two real data examples. Results simulation study investigating performance estimation procedure are presented.
