Bayesian parameter inference by Markov chain Monte Carlo with hybrid fitness measures: theory and test in apoptosis signal transduction network. [PDF]

open access: yesPLoS ONE, 2013
When model parameters in systems biology are not available from experiments, they need to be inferred so that the resulting simulation reproduces the experimentally known phenomena. For the purpose, Bayesian statistics with Markov chain Monte Carlo (MCMC)

Laplace approximation for conditional autoregressive models for spatial data of diseases

open access: yesMethodsX, 2022
Conditional autoregressive (CAR) distributions are used to account for spatial autocorrelation in small areal or lattice data to assess the spatial risks of diseases.

Bayesian inference on reliability parameter with non-identical-component strengths for Rayleigh distribution [PDF]

open access: yesJournal of Mahani Mathematical Research
In this paper, we delve into Bayesian inference related to multi-component stress-strength parameters, focusing on non-identical component strengths within a two-parameter Rayleigh distribution under the progressive first failure censoring scheme.

Seemingly unrelated time series model for forecasting the peak and short-term electricity demand: Evidence from the Kalman filtered Monte Carlo method

open access: yesHeliyon, 2023
In this extant paper, a multivariate time series model using the seemingly unrelated times series equation (SUTSE) framework is proposed to forecast the peak and short-term electricity demand using time series data from February 2, 2014, to August 2 ...

Estimating the Volume of the Solution Space of SMT(LIA) Constraints by a Flat Histogram Method

open access: yesAlgorithms, 2018
The satisfiability modulo theories (SMT) problem is to decide the satisfiability of a logical formula with respect to a given background theory. This work studies the counting version of SMT with respect to linear integer arithmetic (LIA), termed SMT(LIA)

Iran's Exchange Market in Five Episodes: Bayesian Estimation of Systematic Risk with MCMC Method [PDF]

open access: yesMathematics and Modeling in Finance
This paper estimates systematic risk in Iran’s foreign exchange market using a stochastic volatility model, analyzing five distinct episodes shaped by varying economic and political conditions. By tracing the evolution of volatility dynamics across these

MCMC and GLMs for estimating regression parameters: Evidence from non-life Egyptian insurance sector [PDF]

open access: yesJournal of Humanities and Applied Social Sciences, 2019
Purpose – The purpose of this study is to estimate the linear regression parameters using two alternative techniques. First technique is to apply the generalized linear model (GLM) and the second technique is the Markov Chain Monte Carlo (MCMC) method ...

A fast algorithm for BayesB type of prediction of genome-wide estimates of genetic value

open access: yesGenetics Selection Evolution, 2009
Genomic selection uses genome-wide dense SNP marker genotyping for the prediction of genetic values, and consists of two steps: (1) estimation of SNP effects, and (2) prediction of genetic value based on SNP genotypes and estimates of their effects.

Preconditioning Markov Chain Monte Carlo Simulations Using Coarse-Scale Models [PDF]

open access: yes, 2006
We study the preconditioning of Markov chain Monte Carlo (MCMC) methods using coarse-scale models with applications to subsurface characterization. The purpose of preconditioning is to reduce the fine-scale computational cost and increase the acceptance ...
