Quantile regression Order <- See Stata's other features Including median, minimization of sums of absolute deviations There are three ways to obtain the VCE: the standard Koenker and Bassett method appropriate for i.i.d. errors; a Huber sandwich estimator that can be used even if the errors ...
Stata 统计与数据管理软件 IV quantile regression(IV分位数回归) 获取报价申请试用 更新说明 当我们想研究协变量对结果的不同量级的影响,而不仅仅是对精益的影响时,我们使用分位数回归。例如,我们可能对建立学生的年级分布模型感兴趣,以及它如何受到协变量变化的影响。现有的 qreg 命令适合于分位数回归模型,但是如...

Quantile regression: Basics and recent advances J. M.C. Santos Silva University of Surrey 2019 UK Stata Conference 06/09/19 1 1. Summary Quantile regression (Koenker and Bassett, 1978) is increasingly used by practitioners but it is still not part of the standard econometric/statistics courses...
Empirical analyses of quantile regression models are obtained using Stata’s “sreg” command. Due to the economic importance to the global economy (Ahmad et al., 2021), this study focuses on a developed market. Financial turmoil induced by crises may have had a significant impact on profits,...
Hence, this motivates the use of a panel quantile regression estimation approach in the analysis of the fiscal discipline-fiscal federalism nexus in this study. Against this background, this study aims to shed more light on the relationship between fiscal federalism and fiscal discipline from a ...
Stata’s qreg command fits quantile (including median) regression models, also known as least-absolute value (LAV) models, minimum absolute deviation (MAD) models, and L1-norm models.Median regression estimates the median of the dependent variable, conditional on the values of the independent ...
coefficients. The long answer is that you interpret quantile regression coefficients almost just like ordinary regression coefficients.We can illustrate this with a couple of examples using the hsb2 dataset.use http://www.ats.ucla.edu/stat/stata/notes/hsb2, clear tabstat write, by(female) stat...

GRQREG: Stata module to graph the coefficients of a Quantile Regression Description grqreg graphs the coefficients of a quantile regression (Koenker and Basset, 1978). It also has the option to graph the confidence interval, the OLS coefficient and the OLS confidence interval on the same graph. ...
