Relation between Hazard Rate and Fisher Information and Notes due to Fisher Information in Weighted distribution;

Weighted distributions are introduced based on Fislier (1934) and Rao (19(35. l98-r>). In this paper Fisher information tor weighted distributions of exponential family (general case) and weights such as proportional hazard, reversed proportional hazard, order statistics record values, and truncated distributions (special eases) are obtained.
