A Regression Method for Mark-Recapture Estimation of Population Size with Unequal Catchability

摘要: The assumption of equal catchability marked and unmarked animals in mark—recapture sampling is examined. Violation this may come from two basic sources, heterogeneity or contagion, both produce a bias the estimate population size. Two approaches to problem are discussed. First, it noted that can be avoided by statistically independent procedures for marking recapturing. Second, new regression method presented multiple captures on closed population, which combines with "simulated" removal tests whether holds, regardless source bias. Furthermore, if ratio catchabilities between constant over at least successive samples, provides an size even does not hold. suggestions made supplement method. noncapture obtain of...
