New idea for the topological index evaluation and treatise multiple regression with three independent variables. Saturated hydrocarbons used like a model

Abstract

In QSRR discipline an easy novel to used parameter was designed (Vc) for evaluated classical topological index (W, (1)chi, Z, MTI) and two new generation ones (Xu, (1)chi(h)). Regression between Vc and (1)chi(h) presented a correlation index (r) of 0,9992, a surprising high value in comparison with that founds commonly in QSPR/QSAR discipline. Through Vc parameter, an idea to treatise multiple three independent variable regression is present. Model of 35 saturated hydrocarbons were used.
