誰知道這兩個術(shù)語應該怎么翻譯呢? 已有5人參與

我最近在看一本DEGROOT的probability and statistics.關(guān)于概率分布函數(shù)的定義中是這樣寫的 Definition3.1.4 Probability Function/p.f./Support. If a random variable X has a discrete distribution, the probability function (abbreviated p.f.) of X is defined as the function f such that for every real number x, f (x) = Pr(X = x). The closure of the set {x : f (x)>0} is called the support of (the distribution of) X. 這里面的support應該怎么翻譯呢,還有最后那句的closure指的是什么呢,請各位大俠指點迷津,不勝感激! |

Definition3.1.4 Probability Function/p.f./Support. If a random variable X has a discrete distribution, the probability function (abbreviated p.f.) of X is defined as the function f such that for every real number x, f (x) = Pr(X = x). The closure of the set {x : f (x)>0} is called the support of (the distribution of) X. 定義3.1.4概率函數(shù)(縮寫為p.f.)支集。如果隨機變量X有一個離散分布,X的概率函數(shù)(縮寫為p.f.) 定義為函數(shù)f使得對每一個實數(shù)x,f(x)=Pr(X=x)。 集合{x:f(x)>0}的閉包稱作X(的分布)的支集。 support=支集 closure=閉包 |
