Power Prior Elicitation in Bayesian Quantile Regression [PDF]

open access: yesJournal of Probability and Statistics, 2011
We address a quantile dependent prior for Bayesian quantile regression. We extend the idea of the power prior distribution in Bayesian quantile regression by employing the likelihood function that is based on a location-scale mixture representation of ...

Prior elicitation and variable selection for bayesian quantile regression [PDF]

open access: yes, 2013
This thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University.Bayesian subset selection suffers from three important difficulties: assigning priors over model space, assigning priors to all components of the regression

Sparse Quantile Regression [PDF]

open access: yesJournal of Econometrics, 2023
We consider both $\ell _{0}$-penalized and $\ell _{0}$-constrained quantile regression estimators. For the $\ell _{0}$-penalized estimator, we derive an exponential inequality on the tail probability of excess quantile prediction risk and apply it to obtain non-asymptotic upper bounds on the mean-square parameter and regression function estimation ...

Function-on-function linear quantile regression

open access: yesMathematical Modelling and Analysis, 2022
In this study, we propose a function-on-function linear quantile regression model that allows for more than one functional predictor to establish a more flexible and robust approach. The proposed model is first transformed into a finitedimensional space

Quantile Regression with Generated Regressors

open access: yesEconometrics, 2021
This paper studies estimation and inference for linear quantile regression models with generated regressors. We suggest a practical two-step estimation procedure, where the generated regressors are computed in the first step. The asymptotic properties of

Comparison of quantile regression and censored quantile regression methods in the case of chicken consumption

open access: yesDesimal, 2023
The censored quantile regression method is a parameter estimation method that can be used to overcome censored data and BLUE (Best Linear Unbiased Estimator) assumptions that are not met.

A partially collapsed Gibbs sampler for Bayesian quantile regression [PDF]

open access: yes, 2009
We introduce a set of new Gibbs sampler for Bayesian analysis of quantile re-gression model. The new algorithm, which partially collapsing an ordinary Gibbs sampler, is called Partially Collapsed Gibbs (PCG) sampler.

Modified Quantile Regression for Modeling the Low Birth Weight

open access: yesFrontiers in Applied Mathematics and Statistics, 2022
This study aims to identify the best model of low birth weight by applying and comparing several methods based on the quantile regression method's modification.

A Bayesian Binary reciprocal LASSO quantile regression (with practical application)

open access: yesJournal of Kufa for Mathematics and Computer, 2023
Quantile regression is one of the methods that has taken a wide space in application in the previous two decades because of the attractive features of these methods to researchers, as it is not affected by outliers values, meaning that it is considered ...

Pyramid Quantile Regression [PDF]

open access: yesJournal of Computational and Graphical Statistics, 2019
Quantile regression models provide a wide picture of the conditional distributions of the response variable by capturing the effect of the covariates at different quantile levels. In most applications, the parametric form of those conditional distributions is unknown and varies across the covariate space, so fitting the given quantile levels ...
