^aThe root mean-squared error (RMSE) for the constant that best fits the model property. This is also equal to the square root of the variance of that property, calculated over all 1304 LP models.

^bThe number of polynomial terms used in the best fit, as determined using cross-validation (see Materials and Methods).

^cThe RMSE for the final polynomial fit, as evaluated on the test set.

^dThe, R² for the final polynomial fit, as evaluated on the test set.
