Regression for Exploring Rainfall Pattern in Indramayu Regency
Jurnal Ilmu Dasar, 2012 Quantile regression is an important tool for conditional quantiles estimation of a response Y for a given vector of covariates X. It can be used to measure the effect of covariates not only in the center of a distribution, but also in the upper and lower

Journal of the Operations Research Society of Japan, 1991 Summary: This study proposes a new use of goal programming for empirically estimating a regression quantile hyperplane. The approach can yield regression quantile estimates that are less sensitive to not only non- Gaussian error distributions but also a small sample size than conventional regression quantile methods.

Multimorbidity and Associations with Cognition and Alzheimer's Disease Biomarkers
Annals of Neurology, EarlyView.Objective Multimorbidity, the coexistence of 2 or more chronic conditions, has been linked to cognitive aging and Alzheimer's disease (AD) and AD‐related dementias, yet the mechanisms remain unclear. We aimed to examine the associations of multimorbidity with cognition and biomarkers across multiple mechanistic pathways.

Quantile Regression in the Presence of Sample Selection [PDF]
Most sample selection models assume that the errors are independent of the regressors. Under this assumption, all quantile and mean functions are parallel, which implies that quantile estimators cannot reveal any (per definition non-existing ...

Archaeological Prospection, EarlyView.ABSTRACT Burial mounds are key elements of Mediterranean funerary landscapes, but in intensively cultivated coastal plains their low‐relief expression is easily obscured by ploughing, levelling and rapidly changing surface conditions, making single‐date observations unreliable.

Per‐ and Polyfluoroalkyl Substances and Knee Osteoarthritis: Data From the Osteoarthritis Initiative
Arthritis &Rheumatology, EarlyView.Objective To examine whether concentrations of specific per‐ and polyfluoroalkyl substances (PFAS) and a mixture of PFAS relate to incident knee osteoarthritis (KOA) and knee pain progression. Methods Among a case‐cohort sample from the OA Initiative (n = 1,878), we examined associations of serum concentrations of eight PFAS with odds of developing ...

British Journal of Clinical Pharmacology, EarlyView.Abstract Aim Risankizumab is a high‐cost biologic treatment for chronic plaque psoriasis, an immune‐mediated inflammatory disease presenting with painful red scaly skin lesions. Inter‐individual heterogeneity in treatment response may be better addressed with personalised rather than fixed dosing. We sought to develop a pharmacokinetic/pharmacodynamic (

Simulation Study for Variable Selection in Quantile Regression
Wasit Journal for Pure SciencesSix essential techniques for variable selection in quantile regression models are thoroughly examined in this work. Quantile Lasso, gamma-divergence, quantile elastic net, quantile adaptive Lasso, quantile SCAD, and quantile MCP are some of these ...

Biotechnology and Bioengineering, EarlyView.ABSTRACT The agitation power input substantially impacts the oxygen transfer rate in aerobic fermentation processes. Furthermore, in a carbon‐limited process where the substrate feed rate is controlled by the concentration of dissolved oxygen, the power input will consequently govern the feed rate.
