Multivariate Quantile Function Forecaster

open access: yes, 2022
We propose Multivariate Quantile Function Forecaster (MQF$^2$), a global probabilistic forecasting method constructed using a multivariate quantile function and investigate its application to multi-horizon forecasting. Prior approaches are either autoregressive, implicitly capturing the dependency structure across time but exhibiting error accumulation

A Quantile Functions-Based Investigation on the Characteristics of Southern African Solar Irradiation Data

open access: yesMathematical and Computational Applications, 2023
Exploration of solar irradiance can greatly assist in understanding how renewable energy can be better harnessed. It helps in establishing the solar irradiance climate in a particular region for effective and efficient harvesting of solar energy ...

Bayesian analysis of a Tobit quantile regression model [PDF]

open access: yes, 2007
This paper develops a Bayesian framework for Tobit quantile regression. Our approach is organized around a likelihood function that is based on the asymmetric Laplace dis- tribution, a choice that turns out to be natural in this context.

Newdistns: An R Package for New Families of Distributions

open access: yesJournal of Statistical Software, 2016
The contributed R package Newdistns written by the authors is introduced. This package computes the probability density function, cumulative distribution function, quantile function, random numbers and some measures of inference for nineteen families of ...

Extreme Events Analysis Using LH-Moments Method and Quantile Function Family

open access: yesHydrology, 2023
A direct way to estimate the likelihood and magnitude of extreme events is frequency analysis. This analysis is based on historical data and assumptions of stationarity, and is carried out with the help of probability distributions and different methods ...

Estimation in functional linear quantile regression

open access: yes, 2013
This paper studies estimation in functional linear quantile regression in which the dependent variable is scalar while the covariate is a function, and the conditional quantile for each fixed quantile index is modeled as a linear functional of the ...

Vector Quantile Regression: An Optimal Transport Approach [PDF]

open access: yes, 2015
We propose a notion of conditional vector quantile function and a vector quantile regression. A \emph{conditional vector quantile function} (CVQF) of a random vector $Y$, taking values in $\mathbb{R}^d$ given covariates $Z=z$, taking values in $\mathbb{R}

Generic Inference on Quantile and Quantile Effect Functions for Discrete Outcomes [PDF]

open access: yesJournal of the American Statistical Association, 2016
Quantile and quantile effect functions are important tools for descriptive and causal analyses due to their natural and intuitive interpretation. Existing inference methods for these functions do not apply to discrete random variables. This paper offers a simple, practical construction of simultaneous confidence bands for quantile and quantile effect ...

Nonparametric Estimation of Quantile and Quantile Density Function

open access: yesJournal of Biometrics & Biostatistics, 2017
In this article, we derive a new and unique method of estimating quantile and quantile density function, which is based on moments of fractional order statistics. A comparison of the proposed estimators is made with existing popular nonparametric quantile and quantile density estimators, in terms of mean squared error (MSE) for censored and uncensored ...

Uncertainty orders on the sublinear expectation space

open access: yesOpen Mathematics, 2016
In this paper, we introduce some definitions of uncertainty orders for random vectors in a sublinear expectation space. We all know that, under some continuity conditions, each sublinear expectation 𝔼 has a robust representation as the supremum of a ...
