random variables
基本解释
- 随机变量;随机变数
英汉例句
- We often assume in finance that random variables, such as returns, are normally distributed.
我们经常在金融学中假设随机变量,比如回报,是正态分布的。 - Both cost and effort are random variables whose variances will reduce over the lifecycle of the project.
成本和工作是随机变量,需要在项目生命周期中减少它们的方差。 - This refers to random variables that have fat-tailed distributions--random variables that occasionally give you really big outcomes.
这是指随机变量有后尾分布--那些能够偶尔会给你带来非常大的产出的随机变量。 - This refers to random variables that have fat-tailed distributions-- random variables that occasionally give you really big outcomes.
这就表示,服从长尾分布的随机变量,这些数据出现极端值的概率比较大
