The companion command qregplot produces coefficient–quantile plots, allowing researchers to visualize how the coefficients of each covariate change across the outcome conditional distribution.enEstimatorQuantile regressionCovariateQuantileEconometricsMathematicsEstimationStatisticsSyntaxRegression analysisarticle
