Drug Type Metrics

Drug Type Metrics

Drug Type	MAE	MSE	RMSE	R-SE	Best Model
M01AB	0.65	0.97	0.99	0.97	Exponential Smoothing
M01AE	6.87	68.4	8.27	-0.01	ARIMA
N02BA	8.99	112.24	10.59	-0.05	ARIMA and SARIMAX

Summary

For M01AB, Exponential Smoothing has the lowest MAE, MSE, and RMSE, indicating better performance compared to ARIMA and SARIMAX.
For M01AE, ARIMA has the lowest MAE, MSE, and RMSE, suggesting it performs better than SARIMAX and Exponential Smoothing.
For N02BA, ARIMA has the lowest MAE and RMSE, indicating better performance, but SARIMAX has the lowest MSE and positive R-SE, suggesting it might capture the variability better.

In summary, the choice of the best model depends on the specific drug type:

For N02BA, the decision is less clear, and it might depend on the specific emphasis on different metrics (e.g., MSE for precision or RMSE for interpretability). ARIMA and SARIMAX both have their strengths.
