Abstract: By means of the parameter estimation, under the p,q-symmetric entropy loss function, the Bayesian estimation, the minimum risk equ ivalent estimation and the minimax estimation of the exponential distribution were presented. Futhermore, when 0≤c*, d>0; c=c*, d>0, the estimator with the form of [cT+d]-1 is admissible; when c<0 or d<0; 0* and d=0; c>c* and d>0, [cT+d]-1is inadmissible.

Key words: Bayes estimation, equivalent estimation, Minimax estimation, scale parameter, admissibility, p,q-symmetric entropy loss function
