Novel application of Wiener vis-a-vis Szeged indices in predicting polychlorinated biphenyls in the environment

摘要

The paper gives a brief account of the recently introduced Szeged index (Sz). This index has been calculated for a series of polychlorinated biphcnyls and used in predicting their occurrence in the environment. The potential of Sz relative to the Wiener index (W) is critically discussed. The advantage of Sz over W is established by employing regression analysis.
