-
The quantum-chemical descriptors and topological indices have been used in QSAR study of pyrones and the algorithms of "Stepwise regression" and "Leaps and bounds regression" are performed for selection of the variables.The results obtained by using the quasi-Newton neural networks are better than that obtained by multiregression.
