A Bayesian Discovery Procedure.
We discuss a Bayesian discovery procedure for multiple comparison problems. We show that under a coherent decision theoretic framework, a loss function combining true positive and false positive counts leads to a decision rule based on a threshold of the posterior probability of the alternative. Under a semi-parametric model for the data, we show that the Bayes rule can be approximated by the o...
متن کاملA semi-Bayesian study of Duncan's Bayesian multiple comparison procedure
Duncan's Bayesian decision-theoretic multiple comparison procedure requires a decision on the relative magnitudes of losses due to Type I and Type II errors. In this paper, the relative losses are chosen so that the procedure results in weak control of familywise error at the .05 level, i.e. the probability that all hypotheses are accepted is .95 when all hypotheses are true. Duncan's Bayesian ...
متن کاملA Bayesian nonparametric procedure for comparing algorithms
A fundamental task in machine learning is to compare the performance of multiple algorithms. This is usually performed by the frequentist Friedman test followed by multiple comparisons. This implies dealing with the well-known shortcomings of null hypothesis significance tests. We propose a Bayesian approach to overcome these problems. We provide three main contributions. First, we propose a no...
متن کاملBayesian Maximum a Posteriori Multiple Testing Procedure
We consider a Bayesian approach to multiple hypothesis testing. A hierarchical prior model is based on imposing a prior distribution π(k) on the number of hypotheses arising from alternatives (false nulls). We then apply the maximum a posteriori (MAP) rule to find the most likely configuration of null and alternative hypotheses. The resulting MAP procedure and its closely related step-up and st...
متن کاملA stepwise aortic clamp procedure to treat porcelain aorta associated with aortic valve stenosis and hemodialysis.
A 62-year-old man was referred for an aortic-valve surgery because of severe aortic stenosis. Thirty years ago, he had undergone a mitral valve commissurotomy and after 9 years, the valve had been replaced by a mechanical valve. He had been undergoing hemodialysis for the past 8 years. A computed tomographic (CT) scan of the chest and abdomen showed a dense circumferential calcification in the ...
