Abstract:
To estimate the tolerance limit and the tolerance interval of disease incubation,under the theory that the observations(samples)were subject to Poisson distribution,the tolerance limits and tolerance interval of disease incubation were calculated based on beta-distribution with integer parameter.Expressions on the relation were obtained,including the statistics on tolerance limits of both minimum and maximum orders while the tolerance was the difference between minimum and maximum order statistics and the parameters of Poisson distribution on the sample size.Using the incomplete observations as an example,reasonable unit of sample size was considered and chosen.
