Bayesian Lasso-mixed quantile regression [PDF]

open access: yesJournal of Statistical Computation and Simulation, 2012
In this paper, we discuss the regularization in linear-mixed quantile regression. A hierarchical Bayesian model is used to shrink the fixed and random effects towards the common population values by introducing an l1 penalty in the mixed quantile regression check function.

Bayesian quantile regression for single-index models [PDF]

open access: yesStatistics and Computing, 2012
Using an asymmetric Laplace distribution, which provides a mechanism for Bayesian inference of quantile regression models, we develop a fully Bayesian approach to fitting single-index models in conditional quantile regression. In this work, we use a Gaussian process prior for the unknown nonparametric link function and a Laplace distribution on the ...

Bayesian semiparametric additive quantile regression [PDF]

open access: yesStatistical Modelling, 2013
Quantile regression provides a convenient framework for analyzing the impact of covariates on the complete conditional distribution of a response variable instead of only the mean. While frequentist treatments of quantile regression are typically completely nonparametric, a Bayesian formulation relies on assuming the asymmetric Laplace distribution as

bqror: An R package for Bayesian Quantile Regression in Ordinal Models [PDF]

open access: yesThe R Journal, 2021
This article describes an R package bqror that estimates Bayesian quantile regression for ordinal models introduced in Rahman (2016). The paper classifies ordinal models into two types and offers computationally efficient, yet simple, Markov chain Monte ...

A Bayesian Variable Selection Method for Spatial Autoregressive Quantile Models

open access: yesMathematics, 2023
In this paper, a Bayesian variable selection method for spatial autoregressive (SAR) quantile models is proposed on the basis of spike and slab prior for regression parameters.

Bayesian quantile semiparametric mixed-effects double regression models

open access: yesStatistical Theory and Related Fields, 2021
Semiparametric mixed-effects double regression models have been used for analysis of longitudinal data in a variety of applications, as they allow researchers to jointly model the mean and variance of the mixed-effects as a function of predictors ...

Quantity and Quality in Scientific Productivity: The Tilted Funnel Goes Bayesian

open access: yesJournal of Intelligence, 2022
The equal odds baseline model of creative scientific productivity proposes that the number of high-quality works depends linearly on the number of total works.
