Performance of proteochemometric models for prediction of HIV-1 RT drug susceptibility.

In the table I and R represent the descriptors of the inhibitors and the reverse transcriptases, respectively. I×R represents the cross-terms of descriptors of the inhibitor and the reverse transcriptase. R×R represents the intra-reverse transcriptase cross-terms (i.e. cross-terms formed from descriptors of different amino acids in the reverse transcriptase sequences).
