Bayesian adaptive design for device surveillance.
BACKGROUND Postmarket device surveillance studies often have important primary objectives tied to estimating a survival function at some future time $$T$$ with a certain amount of precision. PURPOSE This article presents the details and various operating characteristics of a Bayesian adaptive design for device surveillance, as well as a method for es...
متن کاملBayesian Optimum Design Criterion for Multi Models Discrimination
The problem of obtaining the optimum design, which is able to discriminate between several rival models has been considered in this paper. We give an optimality-criterion, using a Bayesian approach. This is an extension of the Bayesian KL-optimality to more than two models. A modification is made to deal with nested models. The proposed Bayesian optimality criterion is a weighted average, where...
متن کاملAn Efficient Bayesian Optimal Design for Logistic Model
Consider a Bayesian optimal design with many support points which poses the problem of collecting data with a few number of observations at each design point. Under such a scenario the asymptotic property of using Fisher information matrix for approximating the covariance matrix of posterior ML estimators might be doubtful. We suggest to use Bhattcharyya matrix in deriving the information matri...
متن کاملAdaptive Hamiltonian Estimation Using Bayesian Experimental Design
Using Bayesian experimental design techniques, we have shown that for a single twolevel quantum mechanical system under strong (projective) measurement, the dynamical parameters of a model Hamiltonian can be estimated with exponentially improved accuracy over offline estimation strategies. To achieve this, we derive an adaptive protocol which finds the optimal experiments based on previous obse...
متن کاملBayesian Adaptive Optimal Design of Psychology Experiments
Experimentation is fundamental to the advancement of science, whether one is interested in studying the neuronal basis of a sensory process in cognitive neuroscience or assessing the efficacy of a new drug in clinical trials. Adaptive methodologies in experimentation, in which the information learned from each experiment is used to inform subsequent experiments, are particularly attractive beca...
