进行H检验是,如果组数g=3且最小样本的例数大于5或g>3时,则H或近似服从v=g的分布。/ananas/latex/p/2377/ananas/latex/p/912

- 设G是一个文法,S是文法开始符号,如果,则称x为文法G[S]的句型。/ananas/latex/p/231787/ananas/latex/p/846/ananas/latex/p/231788
- A:平面,B:球面,C:旋转椭球面,D:椭球面,E:圆柱面,F:抛物柱面,G:椭圆柱面,H:旋转抛物面,I:圆锥面,J:椭圆锥面,K:马鞍面。则: (1)是____; (2)是______; (3)是______; (4)是______; (5)是______; (6)是______; (7)是______; (8)是______; (9)是______; (10)是______; (11)是______; (12)是______; (13)是______;/ananas/latex/p/1045101/ananas/latex/p/28097/ananas/latex/p/958152/ananas/latex/p/39419/ananas/latex/p/973515/ananas/latex/p/47030/ananas/latex/p/645788/ananas/latex/p/36944/ananas/latex/p/34552/ananas/latex/p/422334/ananas/latex/p/1045357/ananas/latex/p/36098/ananas/latex/p/596597
- 已知z=f(u,v),u=g(x,y),v=h(x,y),则/ananas/latex/p/1998497
- F(A,B,C)=,G(A,B,C)=,则F与G相与的结果为 。/ananas/latex/p/660858/ananas/latex/p/660860
- 设随机变量X服从区间(0, 1)上的均匀分布,求Y=的概率密度函数. 解:由已知可得, X的概率密度为: , 又g(x)=, g'(x)=>0, 即g(x)在R上单调增加. h(y)=w3, h'(y)=w4, α=w5, β=w6, (α<β) . 故 . 这里, w1= , w2= , w3= , (w3写成对数函数lna的形式) w4= ,(w4写成a/b的形式) w5= , w6= ,w7= ,(w7写成a/b形式) w8= ./ananas/latex/p/90145/ananas/latex/p/19991/ananas/latex/p/845215/ananas/latex/p/23546/ananas/latex/p/23546/ananas/latex/p/845154
