Tag loss and the Petersen mark-recapture experiment

摘要: SUMMARY A problem in the Petersen capture-mark-recapture experiment (Seber, 1973, Chapter 3) is possible loss of tags. The effect such a on usual estimate population size and its variance investigated for both single double tagging. When there tagging, correction tag can be made based numbers recaptured that retain one or tags, provided we assume independence Two cases are considered, distinguishable tags nondistinguishable which latter have same rates; new approximately unbiased estimates their introduced. It shown these moderately robust to dependence between two little gained by using
