Notes
21) |
Several references are given in the list of Henry's law constants but not assigned to specific species. |
68) |
Modarresi et al. (2007) use different descriptors for their calculations. They conclude that a genetic algorithm/radial basis function network (GA/RBFN) is the best QSPR model. Only these results are shown here. |
185) |
Value from the validation set for checking whether the model is satisfactory for compounds that are absent from the training set. |
186) |
Experimental value, extracted from HENRYWIN. |
233) |
Calculated with a principal component analysis (PCA); see Suzuki et al. (1992) for details. |
242) |
Temperature is not specified. |
249) |
Yaffe et al. (2003) present QSPR results calculated with the fuzzy ARTMAP (FAM) and with the back-propagation (BK-Pr) method. They conclude that FAM is better. Only the FAM results are shown here. |
273) |
Value from the test set. |
280) |
Value from the training set. |
405) |
The error given by Suzuki et al. (1992) is not the difference between the observed and the calculated value, as it should be. It is unclear which of the numbers is wrong. |
475) |
Calculated under the assumption that ∆G and ∆H are based on [mol L−1] and [atm] as the standard states. |
