Smooth Quantile Normalization [PDF]

open access: yesBiostatistics, 2016
AbstractBetween-sample normalization is a critical step in genomic data analysis to remove systematic bias and unwanted technical variation in high-throughput data. Global normalization methods are based on the assumption that observed variability in global properties is due to technical reasons and are unrelated to the biology of interest. For example,

Realized Quantiles* [PDF]

open access: yesJournal of Business & Economic Statistics, 2021
This paper proposes a simple approach to estimate quantiles of daily financial returns directly from high-frequency data. We denote the resulting estimator as realized quantile (RQ) and use it to forecast tail risk measures, such as Value at Risk (VaR) and Expected Shortfall (ES).

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 ...

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-

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.

Distribution and quantile functions, ranks and signs in dimension d: A measure transportation approach

open access: yesAnnals of Statistics, 2021
Unlike the real line, the real space Rd, for d ≥ 2, is not canonically ordered. As a consequence, such fundamental univariate concepts as quantile and distribution functions, and their empirical counterparts, involving ranks and signs, do not canonically

Role of Export Diversification and Renewable Energy on the Load Capacity Factor in Indonesia: A Fourier Quantile Causality Approach

open access: yesFrontiers in Environmental Science, 2021
Sustainable development and reducing environmental pressure are major issues that concern developed as well as developing countries. Although researchers widely use carbon dioxide emissions and ecological footprint within the scope of environmental ...

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.
