Properties and Implementation of Jeffreys’s Prior in Binomial Regression Models [PDF]

Journal of the American Statistical Association, 2008
We study several theoretical properties of Jeffreys's prior for binomial regression models. We show that Jeffreys's prior is symmetric and unimodal for a class of binomial regression models. We characterize the tail behavior of Jeffreys's prior by comparing it with the multivariate t and normal distributions under the commonly used logistic, probit ...

How endorser attributes influence conservation communication

Conservation Biology, EarlyView.
Abstract Conservation communication often uses the celebrity endorsement strategy. However, robust evidence regarding its effectiveness is still limited. More importantly, practitioners do not have guidelines for selecting an ideal endorser because there is no clear consensus on what endorser attributes are most critical.

A Bayesian model for binary Markov chains

International Journal of Mathematics and Mathematical Sciences, 2004
This note is concerned with Bayesian estimation of the transition probabilities of a binary Markov chain observed from heterogeneous individuals. The model is founded on the Jeffreys' prior which allows for transition probabilities to be correlated.

Evaluating social outcomes of urban bat citizen science: A case study of public knowledge, attitudes, and nature connectedness

Conservation Science and Practice, EarlyView.
Abstract Citizen science is widely used in biodiversity monitoring, yet its application to bats remains limited, particularly regarding how participation influences public understanding and support for conservation. This study examined short‐term changes in ecological knowledge, attitudes toward bats, and connection to nature following participation in

Bayesian Approach of Birnbaum-Saunders Quantile Regression via Jeffreys and Weakly Informative Priors

Proceedings of the International Conference on Applied Innovations in IT
In this article we propose a general Bayesian estimation framework for the Birnbaum-Saunders Quantile Regression (BSQ) model which is used to analyze asymmetric and heterogeneous economic data. In this work, the novel aspect is the joint incorporation of

Objective Bayesian analysis for the accelerated degradation model using Wiener process with measurement errors

Statistical Theory and Related Fields, 2018
The Wiener process as a degradation model plays an important role in the degradation analysis. In this paper, we propose an objective Bayesian analysis for an acceleration degradation Wiener model which is subjected to measurement errors.

Rapid Intrasegmental Progression After Percutaneous Radiofrequency Ablation for Hepatocellular Carcinoma: Incidence, Imaging Features, and Clinical Outcomes

Hepatology Research, EarlyView.
ABSTRACT Aim Radiofrequency ablation (RFA) is curative therapy for early‐stage hepatocellular carcinoma (HCC), but a rare subset of patients develop aggressive intrasegmental recurrence shortly after complete ablation. We characterized the incidence, risk factors, and absolute risk.

Combining eDNA metabarcoding and stable isotope analysis advances diet studies in a colonial, non‐regurgitating seabird

Ibis, EarlyView.
Understanding seabird diet is fundamental to assessing trophic interactions and predicting responses to environmental change. However, seabird diet studies are often constrained by low taxonomic resolution, invasive sampling methods or reliance on opportunistically collected samples, leaving the diet of important populations such as Common Guillemots ...

A Bayesian Approach to Kriging Metamodeling for Computer Experiments

Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2012
In this paper, an efficient and effective Gaussian Kriging metamodeling approach is proposed in the framework of Bayesian maximum a posterior. Different prior densities and particularly, a Jeffreys' noninformative density based hierarchical prior is
