Bayesian quantile regression [PDF]

open access: yesWorking Paper Series, 2005
Recent work by Schennach(2005) has opened the way to a Bayesian treatment of quantile regression. Her method, called Bayesian exponentially tilted empirical likelihood (BETEL), provides a likelihood for data y subject only to a set of m moment conditions of the form Eg(y, θ) = 0 where θ is a k dimensional parameter of interest and k may be smaller ...

Regularized Bayesian quantile regression [PDF]

open access: yesCommunications in Statistics - Simulation and Computation, 2017
A number of nonstationary models have been developed to estimate extreme events as function of covariates. A quantile regression (QR) model is a statistical approach intended to estimate and conduct inference about the conditional quantile functions.

Gibbs sampling methods for Bayesian quantile regression [PDF]

open access: yesJournal of Statistical Computation and Simulation, 2011
This paper considers quantile regression models using an asymmetric Laplace distribution from a Bayesian point of view. We develop a simple and efficient Gibbs sampling algorithm for fitting the quantile regression model based on a location-scale mixture representation of the asymmetric Laplace distribution. It is shown that the resulting Gibbs sampler

Generative AI for Bayesian Computation [PDF]

open access: yesEntropy
Generative Bayesian Computation (GBC) provides a simulation-based approach to Bayesian inference. A Quantile Neural Network (QNN) is trained to map samples from a base distribution to the posterior distribution.

Deep Evidential Learning for Bayesian Quantile Regression [PDF]

open access: yesarXiv.org, 2023
It is desirable to have accurate uncertainty estimation from a single deterministic forward-pass model, as traditional methods for uncertainty quantification are computationally expensive.

Bayesian Spatial Quantile Regression [PDF]

open access: yesJournal of the American Statistical Association, 2011
Tropospheric ozone is one of the six criteria pollutants regulated by the United States Environmental Protection Agency under the Clean Air Act and has been linked with several adverse health effects, including mortality. Due to the strong dependence on weather conditions, ozone may be sensitive to climate change and there is great interest in studying

Comparison of Bayesian and frequentist quantile regressions in studying the trend of discharge changes in several hydrometric stations of the Gorganroud basin in Iran

open access: yesJournal of Water and Climate Change, 2023
This research utilized Bayesian and quantile regression techniques to analyze trends in discharge levels across various seasons for three stations in the Gorganroud basin of northern Iran. The study spanned a period of 50 years (1966–2016).

High-Dimensional Variable Selection for Quantile Regression Based on Variational Bayesian Method

open access: yesMathematics, 2023
The quantile regression model is widely used in variable relationship research of moderate sized data, due to its strong robustness and more comprehensive description of response variable characteristics.
