Abstract

A credible interval prediction problem of a nonstationary Poisson distribution in terms of Bayes decision theory is considered. This is the two-dimensional optimization problem of the Bayes risk function with respect to two variables: upper and lower limits of credible interval prediction. We prove that these limits can be uniquely obtained as the upper or lower percentile points of the predictive distribution under a certain loss function. By applying this approach, the Bayes optimal prediction algorithm for the credible interval is proposed. Using real web traffic data, the performance of the proposed algorithm is evaluated by comparison with the stationary Poisson distribution.
