We consider the problem of numerically evaluating the expected value of a smooth bounded function of a chi-distributed random variable, divided by the square root of the number of degrees of freedom. This problem arises in the contexts of simultaneous inference, the selection and ranking of ...
A. All values are zero B. The values are evenly distributed around zero C. There are no values D. The variable is not defined 相关知识点: 试题来源: 解析 B。解析:期望为零意味着变量的值均匀分布在零的两侧。选项 A 所有值为零不一定导致期望为零;选项 C 没有值不符合概率分布的概念;选项 D...

Answer to: Find the expected value of the function g (X) = X^2, where X is a random variable defined by the density function F_X(x) = ae^-ax u (x),...
The meaning of EXPECTED VALUE is the sum of the values of a random variable with each value multiplied by its probability of occurrence.
aLet X be a numerically valued random variable with expected value u=E(X).Then the variance of X,denoted by V(X),is V(X)=E(x).Note that,by Theorem 1,V(X) is given by V(X)=f(x) where m is the distribution function of X. 让X是一个数值随机变量与期待值u=E (X)。然后X的...
