Reduction of the number of tests by coupling together the sequential and the Bayesian method

We recommend a method which enables us to reduce the number of tests undertaken according to the sequential method. To achieve this, we take into account the opinion of experts who take a view on the likely value of the sought parameter and its dispersion. Thus, by using the Bayes theorem (with 2 parameters), we can merge these data with the ones obtained during tests on the new product, and reduce therefore the number of tests.
