2018-05-07 Quantile regression with scikit-learn.

scikit-learn does not have any quantile regression. statsmodels does have one QuantReg but I wanted to try something I did for my teachings Régression Quantile based on Iteratively reweighted least squares. I thought it was a good case study to turn a simple algorithm into a learner scikit-learn can reused in a pipeline. The notebook Quantile Regression demonstrates it and it is implemented in QuantileLinearRegression.
