Abstract
In this paper, using the notion of a binary Channel Matrix as well known
in Information Theory, we present an equivalent relation between the SPRT
(Sequential Probability Ratio Test) and Bayes’ Updating. Moreover, we show
the relationship between the SPRT and NSPR (New Sequential Probability
Ratio) where a Hidden Markov Model with Poisson process is introduced as
structural change model. And we also provide the change point detection
performance of SPRT and NSPR by experimental results.
