In this video we will introduce quantile regression and see the difference between it and regular linear regression. We shall also compare the graphs of linear and quantile regression. As we shall see, quantile regression has a major advantage over linear regression: robustness.

Could you provide an example of how to run Recentred Influence functions in Python to analyze unconditional partial effects on quantiles within a regression analysis framework (i.e., unconditional quantile regressions)?

My question is why is it necessary though? The prediction from an OLS give you the conditional mean of the normal distribution, we also already have a constant variance, from there we can then calculate any quantile we need.
