摘要: A modification of sieve sampling is proposed that returns a constant sample size. It scheme selects line items with probability proportional to size (PPS) and nearly without replacement. An unbiased estimator the total error amount presented its variance derived. Conditions under which more efficient than PPS replacement are given.
