This package creates SHAP (SHapley Additive exPlanation) visualization plots for ‘XGBoost’ in R. It provides summary plot, dependence plot, interaction plot, and force plot and relies on the SHAP implementation provided by ‘XGBoost’ and ‘LightGBM’.
WebbThe summary plot (a sina plot) uses a long format data of SHAP values. The SHAP values could be obtained from either a XGBoost/LightGBM model or a SHAP value matrix using shap.values. So this summary plot function normally follows the long format dataset obtained using shap.values. If you want to start with a model and data_X, use shap.plot ...

WebbThough the dependence plot is helpful, it is difficult to discern the practical effects of the SHAP values in context. For that purpose, we can plot the synthetic data set with a decision plot on the probability scale. First, we plot the reference observation to establish context. The prediction is probability 0.76.
