Channelling Multimodality Through a Unimodalizing Transport: Warp-U Sampler and Stochastic Bridge Sampling Estimator
Fei Ding, Shiyuan He, David E. Jones +1
Monte Carlo integration is a powerful tool for scientific and statistical computation, but faces significant challenges when the integrand is a multi-modal distribution, even when…
Practical Guidance for Bayesian Inference in Astronomy
Gwendolyn M. Eadie, Joshua S. Speagle, Jessi Cisewski-Kehe +5
In the last two decades, Bayesian inference has become commonplace in astronomy. At the same time, the choice of algorithms, terminology, notation, and interpretation of Bayesian i…
eBASCS: Disentangling Overlapping Astronomical Sources II, using Spatial, Spectral, and Temporal Information
Antoine D. Meyer, David A. van Dyk, Vinay L. Kashyap +4
The analysis of individual X-ray sources that appear in a crowded field can easily be compromised by the misallocation of recorded events to their originating sources. Even with a…
Quantifying Observed Prior Impact
David E Jones, Robert N Trangucci, Yang Chen
We distinguish two questions (i) how much information does the prior contain? and (ii) what is the effect of the prior? Several measures have been proposed for quantifying effectiv…
Functional PCA with Covariate Dependent Mean and Covariance Structure
Fei Ding, Shiyuan He, David E. Jones +1
Incorporating covariates into functional principal component analysis (PCA) can substantially improve the representation efficiency of the principal components and predictive perfo…
Designing Test Information and Test Information in Design
David E. Jones, Xiao-Li Meng
DeGroot (1962) developed a general framework for constructing Bayesian measures of the expected information that an experiment will provide for estimation. We propose an analogous…
Warp Bridge Sampling: The Next Generation
Lazhi Wang, David E. Jones, Xiao-Li Meng
Bridge sampling is an effective Monte Carlo method for estimating the ratio of normalizing constants of two probability densities, a routine computational problem in statistics, ph…
Disentangling Overlapping Astronomical Sources using Spatial and Spectral Information
David E. Jones, Vinay L. Kashyap, David A. van Dyk
We present a powerful new algorithm that combines both spatial information (event locations and the point spread function) and spectral information (photon energies) to separate ph…
