title: The evaluation of limiting dilution assays.
abstract: Theoretical and practical aspects of limiting dilution assays are considered, and the maximum likelihood solution is illustrated by two worked examples. These examples show up the inferiority of the conventional regression analysis, while the advantages of the maximum likelihood over minimum chi-square methods are covered in the discussion. A program, which will perform all the necessary calculations on a pocket calculator, is listed in the Appendix.
