Distribution (probability)
分布(概率)[distributioin(probabi-lity)〕 一系列独立试验的结果、一些随机变量或误差,经常出现在一些相当正规并可预测的模型中。这些模型可以用数学方法表达出来,其中最重要的称为二项分布、正态分布和泊松分布。 二项分布考虑n次独立试验,每一次试验的结果或者是成功S,或者是失败F,其相应的概率分别为P和q一1一P。以S。表示成功的次数。因为共有(艾)种可能的方法来选择;处成功和,一;处失败,所以随机变量S。的概率分布由p‘S。一‘卜{艾)户,、一给出.这里k二。,1,一,n。这就是二项分布,它的数学期望为np.方差为n闪。参阅“概率论”(probability)条。 如果按照第k次试验是成功还是失败来令随机变量X。等于1或。,那么S。二XI+…十X。。因此.根据中心极限定理,此二项分布可以用正态分布来通近。这个特别的情形称为棣美弗一拉普拉斯定理,设 二,一(*一,户)(,:户。)一告定理断言,当n~Qo时,在一个趋于o的百分误差之内,我们有 P{S,二k}一(2万)一“Zexp(一二是/2), P{a
