Uncertainty Evaluation Method of Marine Soil Wave Velocity Prediction Model Based on Point Estimation Method and Bayesian Principle

Journal of Marine Science and Engineering
The spatial variability of soil shear wave velocity (Vs) significantly influences the results of site seismic response analysis. Based on the collected measured Vs values of silty clay in a certain sea area in China, this study divides the Vs data into ...

Analysis of Structural Differences and Asymmetry of Shocks Between the Czech Economy and the Euro Area [PDF]

Statistika: Statistics and Economy Journal, 2016
The goal of this paper is to examine asymmetry of shocks and structural differences between the Czech economy and the euro area. For this purpose I use a New Keynesian DSGE model of two economies.

Bayesian estimation for alpha power Weibull model under adaptive progressive censoring: a comparative study of Metropolis-Hastings and Hamiltonian Monte Carlo methods

Applied Mathematics in Science and Engineering
The alpha power Weibull distribution is a flexible generalization of the classical Weibull distribution that is capable of modeling a wide variety of data behaviors through its ability to accommodate multiple shapes of the hazard rate function.

Exact Posterior distribution of risk ratio in the Kumaraswamy–Binomial model

Comptes Rendus. Mathématique, 2023
In categorical data analysis, the $2\times 2$ contingency tables are commonly used to assess the association between groups and responses, this is achieved by using some measures of association, such as the contingency coefficient, odds ratio, risk ...

Bayesian Sample size Determination for Longitudinal Studies with Continuous Response using Marginal Models

پژوهش‌های ریاضی, 2018
Introduction Longitudinal study designs are common in a lot of scientific researches, especially in medical, social and economic sciences. The reason is that longitudinal studies allow researchers to measure changes of each individual over time and often

Fully Bayesian Experimental Design for Pharmacokinetic Studies

Entropy, 2015
Utility functions in Bayesian experimental design are usually based on the posterior distribution. When the posterior is found by simulation, it must be sampled from for each future dataset drawn from the prior predictive distribution.

Approximating Posterior Distributions by Mixtures

Journal of the Royal Statistical Society Series B: Statistical Methodology, 1993
SUMMARY Kernel density estimation techniques are used to smooth simulated samples from importance sampling function approximations to posterior distributions, resulting in revised approximations that are mixtures of standard parametric forms, usually multivariate normal or T-distributions.

On the Asymptotic Behaviour of Posterior Distributions

Journal of the Royal Statistical Society Series B: Statistical Methodology, 1969
Summary Let a random sample of size n be taken from a distribution having a density depending on a real parameter θ, and let θ have an absolutely continuous prior distribution with density π(θ). We give a rigorous proof that, under suitable regularity conditions, the posterior distribution of θ will, when n tends to infinity, be ...
