Smoothed Weighted Quantile Regression for Censored Data in Survival Analysis

open access: yesAxioms
In this study, we propose a smoothed weighted quantile regression (SWQR), which combines convolution smoothing with a weighted framework to address the limitations.

Linear Quantile Mixed Models: The lqmm Package for Laplace Quantile Regression

open access: yesJournal of Statistical Software, 2014
Inference in quantile analysis has received considerable attention in the recent years. Linear quantile mixed models (Geraci and Bottai 2014) represent a ?exible statistical tool to analyze data from sampling designs such as multilevel, spatial, panel or

Distribution of the lower quantile point estimate in the two-parameter Weibull distribution

open access: yesVojnotehnički Glasnik, 1998
The expression for the distribution density function of the lower quantile point estimate in the two-parameter Weibull distribution has been derived. A method of lower quantile interval estimation has been proposed and then compared to the corresponding ...

A New Three-Parameter Flexible Unit Distribution and Its Quantile Regression Model

open access: yesIEEE Access
This paper introduces a novel Poisson-unit-Weibull (PUW) distribution, which is defined on a unit domain and characterized by three parameters. The PUW distribution is capable of accommodating diverse non-monotone failure rates.

Some Inadmissibility Results for Estimating Quantile Vector of Several Exponential Populations with a Common Location Parameter

open access: yesRevstat Statistical Journal, 2017
Suppose independent random samples are taken from k (≥ 2) exponential populations with a common and unknown location parameter “µ” and possibly different unknown scale parameters σ1,σ2,...,σk respectively.

Low-storage quantile estimation

open access: yes, 1995
Many different approaches have been taken to the problem of low-storage quantile estimation. One approach is based on stochastic approximation. Others, such as minimax and recursive median, are based on trees. The authors compare their computational properties such as storage demands, the ease and speed of computation, as well as statistical properties

Quantile sieve estimates for time series [PDF]

open access: yes, 2007
We consider the problem of estimating the conditional quantile of a time series at time t given observations of the same and perhaps other time series available at time t - 1. We discuss sieve estimates which are a nonparametric versions of the Koenker-Bassett regression quantiles and do not require the specification of the innovation law.
