Theorem 4.1.1 Law of the Unconscious Statistician. Let X be a random variable, and let r be a real valued function of a real variable. If X has a continuous distribution, then if the mean exists. If X has a dis
Distribution(GUD)Normally the mass of a root has a uniform distribution but some have different uniform distributions named Generalized Uniform Distribution (GUD). The characterization result based on expectation of function of random variable has been obtained for generalized uniform distribution. ...
The Expecatation of a function 一个函数的期望,首先这个函数一定是个随机变量的函数,那么其结果也是个随机变量,是随机变量就有分布,所以就有可能有期望。 举个🌰 : 一个家电制造公司制造的电器每年出现故障的比率是XX,XX是一个当前不知道的随机变量,如果我们感兴趣的是这个电器是失效前能运行多久,我们可能会...
Conditional Expectation as a Function of a Random Variable: Remember that the conditional expectation of XX given that Y=yY=y is given by E[X|Y=y]=∑xi∈RXxiPX|Y(xi|y).E[X|Y=y]=∑xi∈RXxiPX|Y(xi|y). Note that E[X|Y=y]E[X|Y=y] depends on the value of yy. In othe...

Best means it is the function of X with the lowest mean squared error (expected squared di↵erence between Y and prediction of Y ). It is called the Minimum Mean Square Estimate (MMSE) Theorem Let X, Y bejointly Normal random variables. Then ...
aIt remains the basis for any further corrupt behavior, whether it is in business or in public administration. The origin of any act of corruption is the fact that some basic principles have become corrupt. 它其中任一进一步保持为腐败行为的依据,它是否在事务或在公共事务管理。 腐败所有行动的起源...
xis the value of the continuous random variableX P(x) is the probability mass function ofX Properties of expectation Linearity When a is constant and X,Y are random variables: E(aX) =aE(X) E(X+Y) =E(X) +E(Y) Constant When c is constant: ...
6) mathematical expectation of fuzzy random varibles 模糊随机变量的数学期望补充资料:设计洪水的期望概率 在每一年内,设计洪水被实际洪水超过的概率。它表示所设计的水利设施在水文上破坏的可能性,因此也称为破坏概率。设以x表示实际洪水,憫p表示设计频率为p的设计洪水真值xp的估计值(因此憫p亦为随机变量),则...
