Thus, for example, if X is distributed as a Poisson random variable with parameter [lambda] being [[mu].sub.x] = [[sigma].sup.2.sub.x] = [lambda], we obtain that the function f(x) = [[integral].sup.x] k[[lambda].sup.-1/2]d[lambda] = [k.sup.*] [square root of x]...

Expected Value of Poisson Random Variable: E[X]=λ PROOF By the definition of expected value, E[X]=∑x∈Im(X)x⋅P(X=x) , where x\in Im (X) simply means that x is one of the possible values of the random variable X . Applying this to the Poisson Distribution, ...
泊松分布的一道题目 Let X be a poisson random variable with mean equal to 10.find E[X^2] 该如何求? 答案 For Poisson variable X,we know that E{X}=λ and Var{X}=λ too. Therefore,E{X^2} = Var{X}+(E{X})^2 = 10+10^2 = 110. 相关推荐 1 泊松分布的一道题目 Let X be a...
