Streszczenie
The problem of posterior regret ${\mit \Gamma }$-minimax estimation under LINEX loss function is considered. A general form of posterior regret ${\mit \Gamma }$-minimax estimators is presented and it is applied to a normal model with two classes of priors. A situation when the posterior regret ${\mit \Gamma }$-minimax estimator, the most stable estimator and the conditional ${\mit \Gamma }$-minimax estimator coincide is presented.
