Streszczenie
The problem of minimax estimation of a parameter when {\theta } is restricted to a finite interval [{\theta }_0,{\theta }_0+m] is studied. The case of a convex loss function is considered. Sufficient conditions for existence of a minimax estimator which is a Bayes estimator with respect to a prior concentrated in two points {\theta }_0 and {\theta }_0+m are obtained. An example is presented.
