摘要：

We compare the Bayesian and classical approaches to the computation of upper limits to rare processes in the presence of background. The comparison is done using a Monte Carlo test, free of Bayesian assumptions. The test shows that the Bayesian calculation is always conservative; this allows its use in the cases where the classical calculation is difficult to perform. The application to the Higgs search at LEP is discussed.
