[求解]不偏估計量的MSE之習題~懇求會數理統計的大大幫個
Apr 13th 2014, 17:27

計算(θ1) ̂、(θ2) ̂、(θ3) ̂、(θ4) ̂的均方誤差(MSE)並比較其大小
(θ1) ̂=2X ̅
(θ2) ̂=X_((n))
(θ3) ̂=〖X_((1))+X〗_((n))
(θ4) ̂=((n+1)/n) (θ2) ̂=((n+1)/n)(X_n ) ̅

由於符號打上去變成這樣怪怪的,所以會大概會這題的或會數理統計的,可以私訊我
s8900771@gmail.com或留下您的信箱,可以把完整的題目傳給你
計算過程可寫下來拍照傳給我
有解出來的人點數一樣會照給,感激不盡~
