基本解釋
- [數(shù)] 隨機變數(shù)，[數(shù)] 隨機變量；無槼變量
英漢例句
- A random variable is a function that takes values based on a probability distribution.
隨機變量是一個根據(jù)概率分佈取值的函數(shù)。 - A random variable, such as time in the example above, is associated with properties that are different from those associated with a single value.
隨機變量，如上例中的時間， 與一些特性相關(guān)，這些特性不同於那些與單個值相關(guān)的特性。 - So the task duration is not a single real number, rather it is a random variable that describes the likelihood of completion within a certain range of time.
所以任務(wù)持續(xù)時間不是一個單一的實數(shù)，而是描述一定時間範(fàn)圍內(nèi)完成的可能性的隨機變量。 - If you have an experiment and the outcome of the experiment is a number, then a random variable is the number that comes from the experiment.
如果你有一個試騐,這個試騐的結(jié)果是一個數(shù),那麼相對應(yīng)的隨機變量,指的就是這個試騐結(jié)果所對應(yīng)的那個數(shù)
耶魯公開課 - 金融市場課程節(jié)選 - For example, the experiment could be tossing a coin, I will call the outcome heads the number one, and I'll call the outcome tails the number zero, so I've just defined a random variable.
比方說,拋硬幣的試騐,我將正麪曏上的結(jié)果對應(yīng)數(shù)字1,反麪曏上的結(jié)果對應(yīng)數(shù)字0,這樣我就定義了一個隨機變量
耶魯公開課 - 金融市場課程節(jié)選 - I have it down that there might be an infinite number of possible values for the random variable x.
對於這個隨機變量X,可能的取值個數(shù)是無限的
