Site LogoEstimating Hypergeometric Population Size


This JavaScript program computes the maximum likelihood estimator of, and conservative confidence intervals for, the population size when a sample of known size is drawn from the population without replacement. The population is assumed to consist of only two types of objects: successes and failures. The number of successes observed in the sample is known, as is the number of successes in the population. The theory underlying the computations can be found in the paper Conservative Confidence Intervals for a Single Parameter by Mark Finkelstein, Howard G. Tucker and Jerry Alan Veeh, which appeared in Communications in Statistics: Theory and Methods volume 29 #8 pages 1911-1928 (2000). The annotated source code is available
