Twenty-nine nanornaterials (atom composition and conditions of syntheses) have been studied. Their characteristics were applied to predictions of Young's modulus values (in GPa). The obtained statistical characteristics of the models are reasonably good, n = 21, r(2) = 0.9757, s = 18.3 GPa, F = 761 (training set) and n = 8, r(2) = 0.8952, r(pred)(2) = 0.8880, s = 34.7 GPa, F = 51 (test set).
