On the converse theorem in statistical hypothesis testing for Markov chains. (English) Zbl 0788.62008

This work is a continuation of the authors’ earlier work, ibid., 623-628 (1993; Zbl 0780.62005), on the converse theorem in statistical hypothesis testing. Here hypothesis testing for two Markov chains is considered. Under the constraint that the first-kind error probability is less than or equal to \(\exp(-rn)\), where \(r\) is a given positive number, the second-kind error probability is minimized. The geodesic that connects the two Markov chains is defined. By analyzing the geodesic, the so- called power exponents are calculated and then represented in terms of Kullback-Leibler divergence.
