How Do Financial Development and Renewable Energy Affect Consumption-Based Carbon Emissions?

open access: yesMathematical and Computational Applications, 2022
This paper bridges the gap in the literature by employing the novel quantile-on-quantile (QQ) approach, the quantile regression approach, and the nonparametric Granger causality test in quantiles to assess the effect of international trade on consumption-

Sampling Importance Resampling Algorithm with Nonignorable Missing Response Variable Based on Smoothed Quantile Regression

open access: yesMathematics, 2023
The presence of nonignorable missing response variables often leads to complex conditional distribution patterns that cannot be effectively captured through mean regression.

Quantile Regression in Space-Time Varying Coefficient Model of Upper Respiratory Tract Infections Data

open access: yesMathematics, 2023
Space-time varying coefficient models, which are used to identify the effects of covariates that change over time and spatial location, have been widely studied in recent years. One such model, called the quantile regression model, is particularly useful

Nonparametric depth and quantile regression for functional data [PDF]

open access: yesBernoulli, 2019
We investigate nonparametric regression methods based on spatial depth and quantiles when the response and the covariate are both functions. As in classical quantile regression for finite dimensional data, regression techniques developed here provide insight into the influence of the functional covariate on different parts, like the center as well as ...

Quantile-dependent expressivity of serum C-reactive protein concentrations in family sets [PDF]

open access: yesPeerJ, 2021
Background “Quantile-dependent expressivity” occurs when the effect size of a genetic variant depends upon whether the phenotype (e.g., C-reactive protein, CRP) is high or low relative to its distribution. We have previously shown that the heritabilities

Fuzzy Semi-Parametric Logistic Quantile Regression Model

open access: yesWasit Journal for Pure Sciences, 2023
In this paper, the fuzzy semi-parametric logistic quantile regression model was studied in the absence of special conditions in the classical regression models.

Nonparametric Functional Data Analysis for Forecasting Container Throughput: The Case of Shanghai Port

open access: yesJournal of Marine Science and Engineering, 2022
Transportation is one of the major carbon sources in China. Container throughput is one of the main influencing factors of ports’ carbon emission budget, and accurate prediction of container throughput is of great significance to the study of carbon ...

Quantile-dependent expressivity of plasma adiponectin concentrations may explain its sex-specific heritability, gene-environment interactions, and genotype-specific response to postprandial lipemia [PDF]

open access: yesPeerJ, 2020
Background “Quantile-dependent expressivity” occurs when the effect size of a genetic variant depends upon whether the phenotype (e.g. adiponectin) is high or low relative to its distribution.

Additive quantile mixed effects modelling with application to longitudinal CD4 count data

open access: yesScientific Reports, 2021
Quantile regression offers an invaluable tool to discern effects that would be missed by other conventional regression models, which are solely based on modeling conditional mean.

Asymmetric impacts of geopolitical risk on stock markets: A comparative analysis of the E7 and G7 equities during the Russian-Ukrainian conflict

open access: yesHeliyon, 2023
In a nonparametric quantile-on-quantile regression model, we analyze the asymmetric financial impact of the Russian-Ukrainian conflict-induced geopolitical risk (GPR) on the top-seven emerging (E7) and developed (G7) stock markets.
