 | | He defines loss functions, risk functions, a priori distributions, Bayes decision rules, admissible decision rules, and minimax decision rules, and proves that a minimax decision rule has a constant risk under certain regularity conditions. |
 | | This and related work was very much aimed at practical applications and his theorems on the distribution of the required number of observations, and on the probabilities associated with errors, found immediate applications. |
 | | His main results on sequential analysis and the theory of decision functions, another topic which was founded by him, were gathered together in his monograph Sequential Analysis (1947). |
