*3.3. Test 3—Influence of Input Variables*

From the application of the ANNs of Test 3 to the 'testdata' database, where the input variables are studied, the ANN with the lowest ME was T3\_07, with an ME of 0.21 min. The ANN with the lowest MAE was T3\_01, with an MAE of 4.85 min. With an MSE of 41.42 min, T3\_01 was the best ANN in this parameter. The smallest maximum error recorded was 20.20 min and occurred in T3\_07. The ANN with the lowest percentage error was T3\_01, like T1\_07 and T2\_15, with a PE of 2.52% (please see Table 5).

From the training of the networks for Test 3, it can be concluded that:
