『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.』 上面是書中的文章,好像是在說明很重要的概念 不過我卻一直搞不懂內容是在說什麼,雖然有點 長,拜託了解的人解釋一下內容的涵意,非常感謝了 -- 夫兵者不祥之器物或惡之故有道者不處君子居則貴左用兵則貴右兵者不祥之器非君子 之器不得已而用之恬淡為上勝而不美而美之者是樂殺人夫樂殺人者則不可得志於天下 矣吉事尚左凶事尚右偏將軍居左上將軍居右言以喪禮處之殺人之眾以哀悲泣之戰勝以 喪禮處之道常無名樸雖小天下莫能臣侯王若能守之萬物將自賓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將知止知 220-133-64-250.HINET-IP.hinet.net海
