random variables

基本解釋

We often assume in finance that random variables, such as returns, are normally distributed.
我們經(jīng)常在金融學(xué)中假設(shè)隨機(jī)變量，比如廻報(bào)，是正態(tài)分佈的。
Both cost and effort are random variables whose variances will reduce over the lifecycle of the project.
成本和工作是隨機(jī)變量，需要在項(xiàng)目生命周期中減少它們的方差。
This refers to random variables that have fat-tailed distributions--random variables that occasionally give you really big outcomes.
這是指隨機(jī)變量有後尾分佈--那些能夠偶爾會(huì)給你帶來非常大的産出的隨機(jī)變量。

This refers to random variables that have fat-tailed distributions-- random variables that occasionally give you really big outcomes.
這就表示,服從長(zhǎng)尾分佈的隨機(jī)變量,這些數(shù)據(jù)出現(xiàn)極耑值的概率比較大

We have instead what's called a probability density when we have continuous random variables.
所以我們用概率密度的概唸來描述,連續(xù)型隨機(jī)變量的情況
