In this communication, we characterize a measure of information of types , , and by taking certain axioms parallel to those considered earlier by Havrda and Charvat along with the recursive relation (; , , ) , ; , , ) (()), ; ,()), ; , ), , , , . Some properties of this measure are also studied. This measure includes Shannon’s information measure as a special case.
