WebbA note about how R 2 is calculated by caret: it takes the straightforward approach of computing the correlation between the observed and predicted values (i.e. R) and squaring the value. When the model is poor, this can lead to differences between this estimator and the more widely known estimate derived form linear regression models. WebbTo visualize SHAP values of a multiclass or multi-output model. To compare SHAP plots of different models. To compare SHAP plots between subgroups. To simplify the workflow, {shapviz} introduces the “mshapviz” object (“m” like “multi”). You can create it in different ways: Use shapviz() on multiclass XGBoost or LightGBM models.

WebbSHAP values are calculated using the marginal contribution of a feature value to a given model. To obtain the overall effect of a given feature value on the final model (i.e. the SHAP value ) it is necessary to consider the marginal contribution of that feature value in all the models where it is present. Webbcomputing interventional SHAP values and interaction val-ues of piecewise linear regression trees. In addition, we have presented an approach to aggregate data to speed up the computation of SHAP values, which enables the tractable calculation of SHAP values for larger datasets without the need for subsampling.
