✦ Synopsis
Random sampling from a finite population of size N =nr (r known) is considered. The statistic observed is !Z$d,=number of observations required until the kth set of size I from the n wta of r is obtained. An asymptotically unbiased estimator of n is obtained together with ita approximate variance. Recommendations are made for choices of r and 1, based on the large sample expectation of !&. An application in archeology to the atimation of the number of individuals originally preeent baaed on multiple bone counts is considered.
