  1. For magnetic moment, only magnetic atoms (with moments greater than 0.5 μB) are considered and included in the test set statistics. The best performing model is highlighted in bold for each property. A correlation coefficient for O 2p-band center element average was not computed as it is not defined for comparison against a single value. The bond-valence method for magnetic moment is not reported, as the parameters were unable to be fit without high error.
