Pearson Correlation and MAPE for all country models. Pearson Correlation and MAPE between the real and the predicted 1-, 3-, and 6-months-ahead GPI values at a country level for all predictive models. The boxplots represent the distribution of the Pearson correlation and MAPE for all country models. The plots’ data points correspond to each country model. Overall, XGBoost outperforms all other models
