The minimax adjustment principle presented in this paper uses the minimax principle in order to improve a given action in the light of some knowledge on the state of the nature or on the other actors. It turns out that the given action is kept unchanged if it can be reconciled with the external...

The classical criteria of the errors of type I and type II are generalized, and this approach is applied to the linear hypothesis in the linear regression model. A...</subscript></subscript>
