Table 9: Statistical, N\(/r^{2}\) (2 nd decimal figure)\(/\)s, results for the eleven properties from Tables 4–7. 2 nd column: MLS, results, 3 rd column: ANN with one hidden neuron (ANN 1 HN) results, 4 th column: ANN with externally chosen number of hidden neurons (ANN enHN) results, 5 th column: ANN with software chosen number of hidden neurons (ANN snHN) results. First line shows the statistical results for the training (MLS) and train plus test (ANN) compounds, the second line shows the overall statistical results inclusive of the evaluated compounds. M stands for MMCIs (otherwise they are MCIs). The last two columns show also the number of hidden neurons (second line, underlined and bold). \begin{table}
