摘要:
A problem in the Petersen capture-mark-recapture experiment (Seber, 1973) is the possible loss of tags. The effect of such a loss on the usual estimate of population size and the estimate of its variance is investigated for both single and double tagging. When there is double tagging, a correction for tag loss can be made based on the numbers recaptured that retain 1 or both tags, provided independence of the tags can be assumed. Two cases are considered, distinguishable tags and nondistinguishable tags in which the latter have the same loss rates; new approximately unbiased estimates of population size and their variance estimates are introduced. These estimates are moderately robust to dependence between the 2 tags, and there is little to be gained by using nondistinguishable tags.
