EXPECTED VALUE在英语中的意思是什么?

期望值

在概率理论中,期望值直观地指的是随机变量的值将会“期望”地发现可以重复无限次数的随机变量处理并获取所获得的值的平均值。 更正式地,期望值是所有可能值的加权平均值。 换句话说,随机变量可以承担的每个可能的值乘以其分配的权重,然后将所得到的乘积相加在一起以找到期望值。 用于计算该平均值的权重是在离散随机变量的情况下的概率,或在连续随机变量的情况下的概率密度函数的值。 从严格的理论观点来看,连续变量的预期值是随机变量相对于其概率测度的积分。 由于概率永远不会为负数,所以预期值与随机变量值乘以该值概率的曲线图下的面积成比例。 因此,对于连续随机变量,期望值是加权和的极限,即积分。

在英语 词典里expected value的定义

字典中的期望值的定义是随机变量或其任何给定函数的所有可能值的总和或积分乘以变量值的相应概率。 符号:E是分布的均值。 E = E-c其中c是常数也称为:数学期望。
