In previous several videos on regression, we pay special attentions on predicting conditional means. Sometimes, we are more interested in medians instead of means. For example, it is more convincing to use median income rather than mean income to draw a better conclusions on income levels of U.S. Here, we show you how to use Stata to estimate conditional median, and other quantiles (such as 25%, 75%, and so on). And Quantile Regression is also important to investigate different effects of independent variables across the whole spectrum of dependent variables.
