A Bayesian estimation of reliability model using the linex loss function
(1994) M. Pandey; V.P. Singh; C.P.L. Srivastava
In this paper the problem of Bayes estimation of the reliability and the shape parameter p of a finite range failure time model is considered (assuming scale parameter θ is known). Following Zellner [A. Zellner, J. Am. Statist. Assoc. 81, 446-451 (1986)] the asymmetric loss function is used to obtain the Bayes estimators. Efficiencies of the proposed Bayes estimators are obtained with respect to the ordinary Bayes estimators and it was found that the proposed Bayes estimators are better than the ordinary Bayes estimators for quite a wide range of parameters. © 1994.
Testing equality of means in a bivariate normal population under possible presence of correlation coefficient
(1990) C.P.L. Srivastava; S.R. Srivastava
In this paper, we have considered for testing the hypothesis H0: μ1 = μ2, in a bivariate normal population N(μ1,μ2,σ2,σ2,ρ{variant}) when it is suspected that correlation coefficient ρ{variant}, may be equal to zero. The expressions for the power and size have been obtained and recommendations regarding use or not of the proposed procedure have also been attempted. © 1990.
