This ...
Mean Absolute Percentage Error (MAPE): MAPE measures the average absolute percentage difference between predicted and actual values. It is particularly useful when the scale or magnitude of the dependent variable varies significantly. Coefficient of Determination (COD): COD is another term for R-square...
