Abstract:   (10789 Views)
In this paper, first the Bhattacharray and Kshirsagar bounds are introduced and then the multiparameter Bhattacharyya bound is presented in simpler and understandable form. Furthermore, the multiparameter Kshirsagar lower bound, which has not been studied yet, is obtained. Finally, by presenting some example of Log-normal distribution, the bounds are computed and compared.
Keywords: Bhattacharrya bound, Cramer-Rao bound, Hammersley-Chapman-Robbins bound, Kshirsagar bound
