期望值

Expected value

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。 In probability theory, the expected value refers, intuitively, to the value of a random variable one would "expect" to find if one could repeat the random variable process an infinite number of times and take the average of the values obtained. More formally, the expected value is a weighted average of all possible values. In other words, each possible value that the random variable can assume is multiplied by its assigned weight, and the resulting products are then added together to find the expected value. The weights used in computing this average are the probabilities in the case of a discrete random variable, or the values of a probability density function in the case of a continuous random variable. From a rigorous theoretical standpoint, the expected value of a continuous variable is the integral of the random variable with respect to its probability measure. Since probability can never be negative, the expected value is proportional to the area under the curve of the graph of the values of a random variable multiplied by the probability of that value. Thus, for a continuous random variable the expected value is the limit of the weighted sum, i.e. the integral.
