✦ Synopsis

The use of the binomial distribution for the numerator and the negative binomial for the denominator in prospective studies leads to an unbiased estimate of relative risk and an unbiased estimate for combining experiments. Optimal sample sizes for groups are calculated and confidence intervals for the relative risk are presented. The efficiency of plans are evaluated by comparing variances and coefficient6 of variation.

In many observed processes, data is fit well by a common distribution except for an excess of numbers of the zero class. This may be due to a threshold phenomenon in which no response occurs until a concomitant variable reaches a certain level, and the response is governed by the common probability
