5.3節完備充分統計量(以c.s.s表示之) 找不符complete的函數g是如何構想出的?感覺找法真奇妙雖然黃文璋也有反例,但看他問讀者為何要這樣找時,我也很想請教怎想的!哈.... 還有...有關指數族定理找為c.s.s時,黃老師書上反例為:當常態分配雙參數均是相同參數時會發現找不到一開矩形,例如N(θ,θ^2);但若為N(μ,σ^2)時,發現可在二維平面的左半平面區域找到矩形,感覺很有趣.請問對於單一參數有無這樣例子?又是不是只要多個參數有相關性就會導致該定理不能使用? 謝謝! -- 一個人澈悟的程度恰等于他所受痛苦的深度 ~~林語堂 -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 59.120.241.229 ※ 編輯: Rotman 來自: 59.120.241.229 (07/19 11:45)
