Analysis of the importance of different energetic terms and the effects of different chemometric protocols has shown how robust models can be obtained. Further work should include the exploration of the effects of including additional descriptors such as those that explicitly describe entropic changes on binding. In addition, it may be possible to obtain improvements in the method by optimizing modelling protocols and tailoring the chemometric tools more specifically towards the data extracted from the molecular systems studied.

Each inhibitor was considered as a single fragment and no intramolecular energy terms were considered. The number of variables per inhibitor was thus equal to 2 (van der Waals and electrostatic) times the number of protein residues ([2 × 99 amino acids] + 1 water molecule) = 398. No variable selection was employed. 1 kcal/mol. This pretreatment reduced the number of variables that entered the PLS analysis to around 50. It is noteworthy that the number of variables was effectively reduced in this example, without the need for variable selection, underscoring the fact that it is possible for a simple pretreatment of the original matrix to accomplish virtually the same effect.
