摘要:
Two possible designs are described for the estimation of the size of populations using the capture‐recapture technique. It is shown that the principle of maximum likelihood applied to one design leads to a biased estimator with infinite expectation and variance, but that applied to the other design it leads to an unbiased estimator; a value for the variance is given in this case. A simulation is described which can be used in the classroom to demonstrate the contrast between the two designs.
