Speaking Stata: Graphing distributions [PDF]
Graphing univariate distributions is central to both statistical graphics, in general, and StataÕs graphics, in particular. Now that Stata 8 is out, a review of official and user-written commands is timely.

Smoothed Weighted Quantile Regression for Censored Data in Survival Analysis
In this study, we propose a smoothed weighted quantile regression (SWQR), which combines convolution smoothing with a weighted framework to address the limitations.

Quantile Regression under Misspecification, with an Application to the U.S. Wage Structure [PDF]
Quantile regression(QR) fits a linear model for conditional quantiles, just as ordinary least squares (OLS) fits a linear model for conditional means. An attractive feature of OLS is that it gives the minimum mean square error linear approximation to the

Quantile Regression Estimates of Confidence Intervals for WASDE Price Forecasts [PDF]
This study uses quantile regressions to estimate historical forecast error distributions for WASDE forecasts of corn, soybean, and wheat prices, and then compute confidence limits for the forecasts based on the empirical distributions.

High quantile function estimation
L'objectif de ce travail est l'estimation d'une fonction quantile extrême. Nous considérons n couples de variables aléatoires indépendants et de même loi qu'un couple (X,Y) à support borné du plan. Notre but est d'estimer le quantile extrême (i.e. d'ordre inférieur à 1/n) de la fonction de répartition conditionnelle de Y sachant que X=x. La fonction de
