Globally local variable importance
- One method with two branches to calculate local variable importance with global models.
- Since the variable importance given by scikit-learn's RandomForestRegressor only shows a global “averaged” variable importance for the whole data set and it is inadequate to represent the variable importance for certain areas or periods (local data set).
- For several months working on this issue, I finally proposed a method with two branches and realised them in python which overcoming the shortcoming of traditional measures. With this method, we did not need to exclusively build local models or geographical approaches to estimate local variable importance and furtherly explore heterogeneity of variable importance.
Hopefully, I upload the codes to get some contribution from developers all over the world. Simutaneously, we wish to obtain some suggestions.
