pdf is a generic function that accepts either a distribution by its name name or a probability distribution object pd. It is faster to use a distribution-specific function, such as normpdf for the normal distribution and binopdf for the binomial distribution. For a list of distribution-specific ...

如果随机变量X的分布列具有上式的形式,则称随机变量X服从二项分布(binomialdistribution),记作XB(〃,p).2.确定一个二项分布模型的步骤:(1)明确伯努利试验及事件A的意义,确定事件A发生的概率p:(2)确定重复试验的次数〃,并判断各次试验的独立性;(3)设X为〃次独立重复试验中事件A发生的次数,则X...
二项分布(binomial distribution )就是对这 类只具有两种互斥结果的离散型随机事件的规律性进行描述的一种概率分布。 考虑只有两种可能结果的随机试验,当成功的概率(π)是恒定的,且各次试验相互 独立,这种试验在统计学上称为贝努里试验(Bernoulli trial )。如果进行 n 次贝努里试验, 取得成功次数为 X (X=0,1, ...

Outline This Section introduces the Poisson distribution, considers its relation to the binomial distribution and looks at how it can be approximated by the normal distribution. The Section continues with a study of the mean and variance of linear combinations of two variables. It concludes with an...
