Webb19 juli 2024 · Context. The Shapley value is an analysis tool for coalitional game in game theory (mathematics), but it can also be paired with the Sobol indices to create a tool to analyze strong correlations [Owen, 2014]. The main idea is that instead of analyzing the participation of each variable at once, you will compute a global-scale variable that will ... WebbTo calculate the Shapley value method we use the predict_parts() function with type = ‘shap’. We need the explainer object and the observation for which we want to calculate the explanation.
