| Abstract: | Researched a class Γ of partial prior information and get some sufficient conditions,under which distribution parameter of the prior parametric distribution can be Γ- admissible estimate under squared-error loss.And the corresponding sufficient condition can be got with respect to classΓprior distribution in restricted space. |

| Keywords: | squared-error loss function Bayesian risk Γ- admissible estimate prior distribution |
