A Comparison of the MPN and Fisher-Yates Estimators for the Density of Organisms |

| Authors: | D. J. Best J. C. W. Rayner |
| Abstract: | The method of moments estimator, discussed in FISHER and YATES (1970), for the density of bacteria is compared with the maximum likelihood or MPN estimator: For sample sizes used in practice the estimators are found to be very similar. Estimators which reduce bias are discussed and their use recommended. |
