  To avoid extensive lab work on properties of chemical compounds, QSPR/QSAR
analysis for topological descriptors is a productive statistical approach to
analyze various physicochemical properties of chemical compounds. Many
researchers have investigated on correlation of degree-based topological
descriptors. In this article we present the predictive ability of 6 well known
degree dependant topological indices of 22 lower poly cyclic aromatic
hydrocarbons in three versions, and we have done a comparison analysis of three
versions of considered topological indices for their predictive ability.
