The quantile regression gives a more comprehensive picture of the effect of the independent variables on the dependent variable. In this presentation, we introduce two Stata commands that allow estimating quantile regression with panel and grouped data. For demonstration purposes, we will utilize the publicly available, built-in Stata By far, codes of this test is neither available in Stata, nor in Eviews. Moreover, the bootstrapped standard errors can Abstract: In this presentation, we introduce two Stata commands that allow estimating quantile regression with panel and grouped data. This robust command provides researchers and analysts with the ability to move beyond standard The -ivqregress- command models quantiles of the outcome and, at the same time, controls for problems that arise from endogeneity.
