Convex Optimization in R

open access: yesJournal of Statistical Software, 2014
Convex optimization now plays an essential role in many facets of statistics. We briefly survey some recent developments and describe some implementations of these methods in R .

Spirometric traits show quantile-dependent heritability, which may contribute to their gene-environment interactions with smoking and pollution [PDF]

open access: yesPeerJ, 2020
Background “Quantile-dependent expressivity” refers to a genetic effect that is dependent upon whether the phenotype (e.g., spirometric data) is high or low relative to its population distribution. Forced vital capacity (FVC), forced expiratory volume in

Outlier Detection using Projection Quantile Regression for Mass Spectrometry Data with Low Replication

open access: yesBMC Research Notes, 2012
Background Mass spectrometry (MS) data are often generated from various biological or chemical experiments and there may exist outlying observations, which are extreme due to technical reasons.

quantreg.nonpar: An R Package for Performing Nonparametric Series Quantile Regression [PDF]

open access: yesThe R Journal, 2016
The R package quantreg.nonpar implements nonparametric quantile regression methods to estimate and make inference on partially linear quantile models. quantreg.nonpar obtains point estimates of the conditional quantile function and its derivatives based on series approximations to the nonparametric part of the model.
