The Bayes Estimators of the Variance and Scale Parameters of the Normal Model With a Known Mean for the Conjugate and Noninformative Priors Under Stein’s Loss [PDF]

open access: goldFrontiers in Big Data, 2022
For the normal model with a known mean, the Bayes estimation of the variance parameter under the conjugate prior is studied in Lehmann and Casella (1998) and Mao and Tang (2012).

Asymmetric Conjugate Priors for Large Bayesian VARs [PDF]

open access: greenSSRN Electronic Journal, 2021
Large Bayesian VARs are now widely used in empirical macroeconomics. One popular shrinkage prior in this setting is the natural conjugate prior as it facilitates posterior simulation and leads to a range of useful analytical results. This is, however, at the expense of modeling flexibility, as it rules out cross‐variable shrinkage, that is, shrinking ...

Calibrating the prior distribution for a normal model with conjugate prior. [PDF]

open access: yesJ Stat Comput Simul, 2014
For a normal model with a conjugate prior, we provide an in depth examination of the effects of the hyperparameters on the long-run frequentist properties of posterior point and interval estimates. Under an assumed sampling model for the data generating mechanism, we examine how hyperparameter values affect the mean squared error (MSE) of posterior ...

Polysaccharide responsiveness is not biased by prior pneumococcal-conjugate vaccination. [PDF]

open access: yesPLoS ONE, 2013
Polysaccharide responsiveness is tested by measuring antibody responses to polysaccharide vaccines to diagnose for humoral immunodeficiency. A common assumption is that this responsiveness is biased by any previous exposure to the polysaccharides in the ...

Conjugate Priors for Exponential Families [PDF]

open access: bronzeThe Annals of Statistics, 1979
Let $X$ be a random vector distributed according to an exponential family with natural parameter $\theta \in \Theta$. We characterize conjugate prior measures on $\Theta$ through the property of linear posterior expectation of the mean parameter of $X : E\{E(X|\theta)|X = x\} = ax + b$.

Conjugate priors and bias reduction for logistic regression models

open access: greenStatistics & Probability Letters, 2022
Logistic regression models for binomial responses are routinely used in statistical practice. However, the maximum likelihood estimate may not exist due to data separability. We address this issue by considering a conjugate prior penalty which always produces finite estimates.

Bayesian inference for Pareto distribution with prior conjugate and prior non conjugate [PDF]

open access: goldJurnal Matematika, Statistika dan Komputasi, 2020
The purpose of this study is to determine the best estimator for estimating the shape   parameters of the Pareto distribution with the known  scale parameter. Estimation of these parameters is done by using the Gamma distribution as the prior distribution of the conjugate and the Uniform distribution as the non-conjugate prior distribution.

Bayesian Analysis of Occupational Exposure Data with Conjugate Priors [PDF]

open access: bronzeAnnals of Work Exposures and Health, 2017
Bayesian analysis is a flexible method that can yield insight into occupational exposures as the methods quantify plausible values for exposure parameters of interest, such as the mean, variance, and specific percentiles of the exposure distribution. We describe three Bayesian analysis methods for the analysis of normally distributed data (e.g.

Enriched conjugate and reference priors for the Wishart family on symmetric cones [PDF]

open access: bronzeThe Annals of Statistics, 2003
A general Wishart family on a symmetric cone is a natural exponential family (NEF) having a homogeneous quadratic variance function. Using results in the abstract theory of Euclidean Jordan algebras, the structure of conditional reducibility is shown to hold for such a family, and we identify the associated parameterization $\phi$ and analyze its ...
