Table 4

Explained variance from cross-validation of four different models using different available inputs applied to two different regression approaches (stepwise-multivariate linear regression [S-MLR] and random forest regression [RFR]) across three years (2019 to 2021). The models were recalibrated for each year before cross-validation using relevant available variables. The best-performing model in each year is indicated in bold; RFR results are in italics.
