摘要

This paper formulates the trade-off between the sample size and the reliability of decisions in a multihypothesis test with possible model errors. We introduce a measure of model uncertainty and derive the best error exponent for the decision error probabilities for allowed levels of model uncertainty. For small deviations from the correct model, the error exponent for sequential probability ratio tests is quantified.
