Data-driven Informative Priors for Bayesian Inference with Quasiperiodic Data

open access: yesThe Astronomical Journal
Bayesian computational strategies for inference can be inefficient in approximating the posterior distribution in models that exhibit some form of periodicity.

Copula Approximate Bayesian Computation Using Distribution Random Forests

open access: yesStats
Ongoing modern computational advancements continue to make it easier to collect increasingly large and complex datasets, which can often only be realistically analyzed using models defined by intractable likelihood functions.

Posterior Distributions for Multivariate Normal Parameters

open access: yesJournal of the Royal Statistical Society Series B: Statistical Methodology, 1963
SUMMARY A class of Bayes posterior distributions is obtained for the parameters of the multivariate normal distribution. These are compared with their fiducial and confidence counterparts.

Survey Design, Symmetry and Posterior Distributions

open access: yesJournal of the Royal Statistical Society Series B: Statistical Methodology, 1973
Summary It is now well known that the sample design is irrelevant in a Bayesian analysis of survey data provided the units are labelled and the sampling is non-informative. However, information about the labels is often not available for the analysis, and in this situation the design will contain information about the labelling and hence

A Bayesian Inference Method and its Application in Fatigue Crack Life Prediction

open access: yesIEEE Access, 2019
In practical engineering, the design data are uncertain. The data will deviate from the true value due to technical reasons such as measurement. It would result in the inaccuracy of crack fatigue life prediction. To deal with those problems, a regression

Bayesian inverse analysis of unsaturated slope parameters using fine-tuned deep operator network model

open access: yesYantu gongcheng xuebao
Bayesian method infers the posterior distribution of slope parameters by combining prior distribution with filed time-series monitoring data. This process requires extensive computational resources due to repeated calls to time-consuming numerical models.

Accurate Bayesian phylogenetic point estimation using a tree distribution parameterized by clade probabilities.

open access: yesPLoS Computational Biology
Bayesian phylogenetic analysis with MCMC algorithms generates an estimate of the posterior distribution of phylogenetic trees in the form of a sample of phylogenetic trees and related parameters.
