【Abstract】 The theory of expectation estimation is put forward to discuss the quality estimation of the domain of expectation. It is demonstrated that the " validity" criterion of the theory of estimation in mathematical statistics (named classic estimate later) isn’t right and arithmetical average value x isn’t the best estimate. The means of characteristic value estimate (N(0, 1) estimate) is suggested to demonstrate that the domain of expectation estimate has the quality of containment and that classic estimate is boundary estimate of the domain of expectation estimate. It is also discussed that the relationship between the theory of probability and the theory of estimation is reciprocal .更多还原
