Spatial Quantile Regression [PDF]

open access: yesComparative Economic Research, 2012
In a number of applications, a crucial problem consists in describing and analyzing the influence of a vector Xi of covariates on some real-valued response variable Yi.

Local Quantile Regression [PDF]

open access: yesJournal of Statistical Planning and Inference, 2010
Quantile regression is a technique to estimate conditional quantile curves. It provides a comprehensive picture of a response contingent on explanatory variables.

Factorisable Multitask Quantile Regression [PDF]

open access: yesSSRN Electronic Journal, 2020
A multivariate quantile regression model with a factor structure is proposed to study data with many responses of interest. The factor structure is allowed to vary with the quantile levels, which makes our framework more flexible than the classical ...

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 ...

Censored Quantile Regression Redux [PDF]

open access: yesJournal of Statistical Software, 2008
Quantile regression for censored survival (duration) data offers a more flexible alternative to the Cox proportional hazard model for some applications. We describe three estimation methods for such applications that have been recently incorporated into ...

Stress Testing German Industry Sectors: Results from a Vine Copula Based Quantile Regression

open access: yesRisks, 2017
Measuring interdependence between probabilities of default (PDs) in different industry sectors of an economy plays a crucial role in financial stress testing. Thereby, regression approaches may be employed to model the impact of stressed industry sectors

Sparse Quantile Regression [PDF]

open access: yesJournal of Econometrics, 2020
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.
