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.

Batch effects removal for microbiome data via conditional quantile regression

open access: yesNature Communications, 2022
Batch effects in microbiome data arise from differential processing of specimens and can lead to spurious findings and obscure true signals. Strategies designed for genomic data to mitigate batch effects usually fail to address the zero-inflated and over-

Crude oil prices and clean energy stock indices: Lagged and asymmetric effects with quantile regression

open access: yesRenewable Energy, 2021
Unlike previous studies examining the association between crude oil and renewable energy stock prices under average conditions, we employ a quantile-based regression approach offering a more comprehensive dependence structure under diverse market ...

Smoothing Quantile Regressions [PDF]

open access: yesJournal of Business & Economic Statistics, 2019
We propose to smooth the entire objective function, rather than only the check function, in a linear quantile regression context. Not only does the resulting smoothed quantile regression estimator yield a lower mean squared error and a more accurate Bahadur-Kiefer representation than the standard estimator, but it is also asymptotically differentiable.

Quantile regression in high-dimension with breaking [PDF]

open access: yesJournal of Statistical Theory and Applications (JSTA), 2013
The paper considers a linear regression model in high-dimension for which the predictive variables can change the influence on the response variable at unknown times (called change-points).

Nonparametric Smoothing for Extremal Quantile Regression with Heavy Tailed Data

open access: yesRevstat Statistical Journal, 2021
In several different fields, it is interested in analyzing the upper or lower tail quantile of the underlying distribution rather than mean or center quantile.

Nonparametric C- and D-vine-based quantile regression

open access: yesDependence Modeling, 2022
Quantile regression is a field with steadily growing importance in statistical modeling. It is a complementary method to linear regression, since computing a range of conditional quantile functions provides more accurate modeling of the stochastic ...

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).

The dynamic effect of information and communication technology and renewable energy on CO2 emission: Fresh evidence from panel quantile regression

open access: yesFrontiers in Environmental Science, 2022
Graphical Abstract Over the last few years, the rapid growth of information and communication technologies (ICT) has contributed to every sector of the economy; however, the environmental consequences of ICT should not be overlooked.
