Any other information on results incl. tables

Currently there is no universally accepted definition of model domain. However, users may wish to consider the possibility that property estimates are less accurate for compounds outside the Molecular Weight range of the training set compounds, and/or that have more instances of a given fragment than the maximum for all training set compounds. It is also possible that a compound may have a functional group(s) or other structural features not represented in the training set, and for which no fragment coefficient was developed. These points should be taken into consideration when interpreting model results.

The complete training sets for MPBPWIN's estimation methodology are not available. Therefore, describing a precise estimation domain for this methodology is not possible. However, a test set of 5890 compounds with available normal boiling points was collected from the PHYSPROP Database that is included with the EPI Suite. Various compounds having boiling points were excluded (most inorganic compounds, compounds using reduced pressures).

The number of compounds used to derive each of the Stein and Brown descriptors can be obtained, but the maximum number of each descriptor that occurs in each compound is not available. The current applicability of the MPBPWIN methodology is best described by its accuracy in predicting boiling point as described in the Accuracy section.
