The best 2D - QSAR model showed suitable statistical measures [ n = 18 ; s = 0 . 11 ; F = 42 . 19 ; R ( 2 ) = 0 . 90 and Q ( 2 ) = 0 . 77 ( SDEP = 0 . 15 ) ] , and according to the optimum 3D - QSAR model [ R ( 2 ) = 0 . 98 , Q ( 2 ) = 0 . 93 ( SDEP = 0 . 08 ) ] , three latent variables explained 62 % of the total variance from original data .
