+      "Bayesian analysis used here to answer the question: \"when
+looking at resampling results, are the differences between models
+'real'?\" To answer this, a model can be created were the performance
+statistic is the resampling statistics (e.g.  accuracy or RMSE).
+These values are explained by the model types.  In doing this, we can
+get parameter estimates for each model's affect on performance and
+make statistical (and practical) comparisons between models.  The
+methods included here are similar to Benavoli et al (2017)
