Abstract

We compare two different methods, classical and Bayesian, for determining confidence intervals involving Poisson-distributed data. We are specifically concerned with cases where the number of counts observed is small and is comparable to the mean number of background counts. We give our reasons for preferring the Bayesian over the classical method. Tables of confidence limits calculated by the Bayesian method are provided for quick reference.
