%0 Journal Article %T On `useful' relative information and J-diver-gence measures %A D. S. Hooda %A A. Ram %J Tamkang Journal of Mathematics %D 2002 %I Tamkang University %R 10.5556/j.tkjm.33.2002.149-160 %X In the present paper some new generalized measures of useful relative information have been defined and their particular cases have been studied. From these measures new useful information measures have also been derived. We have obtained useful measures of inaccuracy, dependence and J-divergence corresponding to each measure of useful relative information. In the end, an equality satisfied by useful J-divergence has been proved. %U http://journals.math.tku.edu.tw/index.php/TKJM/article/view/294
