Story Title

Alternative to Q-Q plot to evaluate regression results

Changes made

Added two functions to create plots to the RegressionEvaluator:

  • plot_residuals():
    • plots the residual vs the actual values.
    • plots also the 0 line to see if we are above or ben
  • plot_residuals_by_bin():
    • plots the residual vs the actual values binned.
    • binning strategy can be: uniform or quantile
    • number of bins can be chosen

How does the solution address the problem

Those two plots should be easier to interpret as the normal QQ-plot and thus can bring more value to discussions with business stakeholders.
