Reproducing kernel‐based functional linear expectile regression [PDF]
Expectile regression is a useful alternative to conditional mean and quantile regression for characterizing a conditional response distribution, especially when the distribution is asymmetric or when its tails are of interest. In this article, we propose

Composite Expectile Regression with Gene-environment Interaction [PDF]
If error distribution has heteroscedasticity, it voliates the assumption of linear regression. Expectile regression is a powerful tool for estimating the conditional expectiles of a response variable in this setting.

Efficient Distributed Learning for Large-Scale Expectile Regression With Sparsity
High-dimensional datasets often display heterogeneity due to heteroskedasticity or other forms of non-location-scale covariance effects. When the size of datasets becomes very large, it may be infeasible to store all of the high-dimensional datasets on ...

Abstract In this work, we intersect data on size‐selected particulate matter (PM) with vehicular traffic counts and a comprehensive set of meteorological covariates to study the effect of traffic on air quality. To this end, we develop an M‐quantile regression model with Lasso and Elastic Net penalizations.

Multivariate Expectiles, Expectile Depth and Multiple-Output Expectile Regression
Despite the importance of expectiles in fields such as econometrics, risk management, and extreme value theory, expectile regression unfortunately remains limited to single-output problems.

Large-Scale Expectile Regression With Covariates Missing at Random
Analysis of large volumes of data is very complex due to not only a high level of skewness and heteroscedasticity of variance but also the phenomenon of missing data.

Modeling uncertainty in financial tail risk: A forecast combination and weighted quantile approach
Abstract A novel forecast combination and weighted quantile‐based tail risk forecasting framework is proposed, aiming to reduce the impact of modeling uncertainty. The proposed approach is based on a two‐step estimation procedure. The first step involves the combination of value‐at‐risk (VaR) forecasts at a grid of quantile levels.

GHG Global Emission Prediction of Synthetic N Fertilizers Using Expectile Regression Techniques
Agriculture accounts for a large percentage of nitrous oxide (N2O) emissions, mainly due to the misapplication of nitrogen-based fertilizers, leading to an increase in the greenhouse gas (GHG) footprint.

Less disagreement, better forecasts: Adjusted risk measures in the energy futures market
Abstract This paper develops a generic adjustment framework to improve in the market risk forecasts of diverse risk forecasting models, which indicates the degree to which risk is under‐ and overestimated. In the context of the energy commodity market, a market in which tail risk management is of crucial importance, the empirical analysis shows that ...
