ON THE ACCEPT-REJECT MECHANISM FOR metropolis-hastings algorithms
收藏 引用
ANNALS OF APPLIED PROBABILITY 2023年 第6B期33卷 5279-5333页
作者: Glatt-holtz, Nathan Krometis, Justin Mondaini, Cecilia Tulane Univ Dept Math New Orleans LA 70118 USA Virginia Tech Natl Secur Inst Blacksburg VA USA Virginia Tech Dept Math Blacksburg VA USA Drexel Univ Dept Math Philadelphia PA USA
This work develops a powerful and versatile framework for determin-ing acceptance ratios in metropolis-hastings-type Markov kernels widely used in statistical sampling problems. Our approach allows us to derive new cl... 详细信息

An Efficient Sampling Algorithm for Non-smooth Composite Potentials
收藏 引用
JOURNAL OF MACHINE LEARNING RESEARCH 2022年 第1期23卷 1-50页
作者: Mou, Wenlong Flammarion, Nicolas Wainwright, Martin J. Bartlett, Peter L. Univ Calif Berkeley Dept EECS Berkeley CA 94720 USA Ecole Polytech Fed Lausanne Sch Comp & Commun Sci CH-1015 Lausanne Switzerland Univ Calif Berkeley Dept Stat Berkeley CA 94720 USA
We consider the problem of sampling from a density of the form p(x) ? exp(-f (x) - g(x)), where f : Rd-+ R is a smooth function and g : R-d-+ R is a convex and Lipschitz function. We propose a new algorithm based on t... 详细信息

Extending computations for disparity testing when data sources are uncertain
收藏 引用
HEALTH SERVICES AND OUTCOMES RESEARCH METHODOLOGY 2023年 第2期23卷 207-226页
作者: McDonald, Gary C. Oakley, Rachel H. Oakland Univ Dept Math & Stat Rochester MI 48063 USA
The topic of this article is one-sided hypothesis testing on the means of two populations when there is uncertainty as to which population a datum is drawn. Along with each datum, a probability is given as to which of... 详细信息

A Bayesian Mixture Model Approach to Disparity Testing
收藏 引用
Applied Mathematics 2024年 第3期15卷 214-234页
作者: Gary C. McDonald Department of Mathematics and Statistics Oakland University Rochester USA
The topic of this article is one-sided hypothesis testing for disparity, i.e., the mean of one group is larger than that of another when there is uncertainty as to which group a datum is drawn. For each datum, the unc... 详细信息

Parameter estimation of gravitational waves with a quantum metropolis algorithm
收藏 引用
CLASSICAL AND QUANTUM GRAVITY 2023年 第4期40卷 045001-045001页
作者: Escrig, Gabriel Campos, Roberto Casares, Pablo A. M. Martin-Delgado, M. A. Univ Complutense Madrid Dept Fis Teor Madrid Spain Quasar Sci Resources SL Madrid Spain Univ Politecn Madrid CCS Ctr Computat Simulat Madrid Spain
After the first detection of a gravitational wave in 2015, the number of successes achieved by this innovative way of looking through the Universe has not stopped growing. However, the current techniques for analyzing... 详细信息

An efficient sampling algorithm for non-smooth composite potentials
The Journal of Machine Learning Research
收藏 引用
The Journal of Machine Learning Research 2022年 第1期23卷 10611-10660页
作者: Wenlong Mou Nicolas Flammarion Martin J. Wainwright Peter L. Bartlett Department of EECS University of California Berkeley Berkeley CA School of Computer and Communication Sciences EPFL Lausanne Switzerland Department of EECS and Department of Statistics University of California Berkeley Berkeley CA
We consider the problem of sampling from a density of the form p(x) ∝ exp(-f(x) - g(x)), where f : ℝd → ℝ is a smooth function and g : ℝd → ℝ is a convex and Lipschitz function. We propose a new algorithm based on ... 详细信息

Weak convergence and optimal tuning of the reversible jump algorithm
收藏 引用
MATHEMATICS AND COMPUTERS IN SIMULATION 2019年 161卷 32-51页
作者: Gagnon, Philippe Bedard, Mylene Desgagne, Alain Univ Oxford Dept Stat 24-29 St Giles Oxford OX1 3LB England Univ Montreal Dept Math & Stat CP 6128Succursale Ctr Ville Montreal PQ H3C 3J7 Canada Univ Quebec Montreal Dept Math CP 8888Succursale Ctr Ville Montreal PQ H3C 3P8 Canada
The reversible jump algorithm is a useful Markov chain Monte Carlo method introduced by Green (1995) that allows switches between subspaces of differing dimensionality, and therefore, model selection. Although this me... 详细信息

STATISTICS & PROBABILITY LETTERS 2016年 117卷 72-79页
作者: Herve, Loic Ledoux, James INSA Rennes IRMAR F-35042 Rennes France CNRS UMR 6625 F-35708 Rennes France Univ Bretagne Loire Rennes France
Let pi be a positive continuous target density on R. Let P be the metropolis-hastings operator on the Lebesgue space L-2 (pi) corresponding to a proposal Markov kernel Q on R. When using the quasi-compactness method t... 详细信息

An Empirical Study of an Adaptive Langevin Algorithm for Bounded Target Densities
收藏 引用
Journal of Data Science 2013年 第3期11卷 501-536页
作者: Christopher H. Mehl OMNITEC Solutions Inc
Markov chain Monte Carlo simulation techniques enable the application of Bayesian methods to a variety of models where the posterior density of interest is too difficult to explore analytically. In practice, however, ... 详细信息

COMMUNICATIONS IN STATISTICS-THEORY AND METHODS 2011年 第1期40卷 159-175页
作者: Chen, Guo Tsurumi, Hiroki Rutgers State Univ Dept Econ New Brunswick NJ 08901 USA
Monte Carlo experiments are conducted to compare the Bayesian and sample theory model selection criteria in choosing the univariate probit and logit models. We use five criteria: the deviance information criterion (DI... 详细信息
