Investigating the impacts of technological innovation and renewable energy on environmental pollution in countries selected by the International Renewable Energy Agency: A quantile regression approach [PDF]

open access: yesCaspian Journal of Environmental Sciences, 2020
Investigating the factors affecting CO2 emissions has always been a challenge. One problem with existing studies is that these studies have been relied on mean-based regression approaches, such as ordinary least squares (OLS) or instrumental variables ...

Ensemble quantile classifier [PDF]

open access: yesComputational Statistics & Data Analysis, 2020
Both the median-based classifier and the quantile-based classifier are useful for discriminating high-dimensional data with heavy-tailed or skewed inputs. But these methods are restricted as they assign equal weight to each variable in an unregularized way.

Estimation of confidence intervals for quantiles in a finite population

open access: yesMathematical Modelling and Analysis, 2008
Confidence intervals provide a way of reporting an estimate of a population quantile along with some information about the precision of estimates. Some procedures that may be used to obtain estimates of confidence intervals for quantiles in a finite ...

Estimating and Forecasting Conditional Risk Measures with Extreme Value Theory: A Review

open access: yesRisks, 2018
One of the key components of financial risk management is risk measurement. This typically requires modeling, estimating and forecasting tail-related quantities of the asset returns’ conditional distribution.

Estimation des pluies journalières extrêmes supérieures à un seuil en climat tropical : cas de la Côte d'Ivoire

open access: yesPhysio-Géo, 2016
The extreme rainfalls are the weather hazards that cause much damage and many casualties. The estimation of extreme rainfall is therefore of great interest to anticipate disasters such as floods and allow thoughtful planning of the territory.

A Quantile-Based Approach for Transmission Expansion Planning

open access: yesIEEE Access, 2020
Transmission expansion planning is an integral part of power system planning and consists of generating and selecting transmission proposals for maintaining sufficient transmission capacity to satisfy the electric load.

ggplot2 Compatible Quantile-Quantile Plots in R [PDF]

open access: yesThe R Journal, 2019
Q-Q plots allow us to assess univariate distributional assumptions by comparing a set of quantiles from the empirical and the theoretical distributions in the form of a scatterplot. To aid in the interpretation of Q-Q plots, reference lines and confidence bands are often added.
