『Bayes estimator provide a tool for solving minimax problems. Thus Bayesian considerations are helpful when choosing an optimal frequentist estimator. Viewed in this light, there is a synthesis of the two approaches. The Bayesian approach provides us with a mean of constructing an estimator that has optimal frequentist properties. This synthesis highlights important features of both the Bayesian and frequentist approaches. The Bayesian paradigm is well suited for the construction of possibly optimal estimators, but is less well suited for their evaluation. The frequentist oaradigm is complementary, as it is well suited for risk evaluations, but less well suited for construction. It is important to view these two approaches and hence "Average risk optimality" and "Minimaxity and admissibility" as complementary rather than adversarial; together they provide a rich set of tools and techniques for the statisticaian.』 上面是书中的文章,好像是在说明很重要的概念 不过我却一直搞不懂内容是在说什麽,虽然有点 长,拜托了解的人解释一下内容的涵意,非常感谢了 -- 夫兵者不祥之器物或恶之故有道者不处君子居则贵左用兵则贵右兵者不祥之器非君子 之器不得已而用之恬淡为上胜而不美而美之者是乐杀人夫乐杀人者则不可得志於天下 矣吉事尚左凶事尚右偏将军居左上将军居右言以丧礼处之杀人之众以哀悲泣之战胜以 丧礼处之道常无名朴虽小天下莫能臣侯王若能守之万物将自宾天地相合以降甘露民莫 之令而自均始制有名名亦既有夫亦将知止知 220-133-64-250.HINET-IP.hinet.net海
