将二项式分布推广到多项式分布(Multinomial Distribution),二项式分布式n次伯努利实验,规定了每次的实验结果只有两个。现在还是做n次实验,只不过每次实验的结果变成了m个,且m个结果发生的概率互斥且和为1,则发生其中一个结果X次的概率就是多项式分布。 扔骰子是典型的多项式分布。骰子有6个面对应6个不同的点数,这样单...
The motions of comets and neutron stars have been integrated over five billion years in the Galactic potential to determine a gamma-ray burst distribution, presuming that bursts are the result of interactions between these two families of objects. The comets originate in two distinct populations - ...
论文加分❗️9种数据分布应用 | ⚖️均匀分布 (Uniform Distribution) 1⃣ 适用于概率等可能发生的场合,无样本量限制。 2⃣ 适用场景:随机抽样、质量控制。 3⃣ 例子:掷骰子、随机选择电话号码。 泊松分布 (Poisson Distribution) 1⃣ 描述稀有事件次数,适用于大样本。
Further, it is shown that these distributions share certain distributional properties with Wishart distribution. Finally, the joint distributions of eigenvalues are obtained. For the sake of readability, the latter two aspects are presented only for Gaussian Hypergeometric distribution.doi:10.1080/...
For certain patterns of T the implied restrictions on the parameter space of the desired multivariate gamma distribution are discussed; in particular the scheme does not allow negative covariances.doi:10.1080/00401706.1977.10489525Gerd Ronninga Fachbereich Wirtschaftswissenschaft und Statistik Universit?t ...

In this paper we propose to approximate the waiting time distribution function (DF) of the waiting customers in a M/G/1-infin queuing system by a gamma-distribution whose parameters alpha and beta are set by means of the first and second moment of the waiting time that are obtained from ...
The lower incomplete function is particularly important in statistics, as it appears in the distribution function of the Chi-square and Gamma distributions. Interactive calculator for lower and upper incomplete Gamma functions Argument z Bound of integration x Standardized lower incomplete Standardized ...
E(X)=p, E(X2)=q , Var(X)=pq 二、二项分布: n次Bernoulli试验的结果中,每次试验的分布不变,结果为1的次数 X 的分布。就是重复n次的伯努利实验。 在概率论和统计学里面,带有参数n和p的二项分布表示的是n次独立试验的成功次数的概率分布。在每次独立试验中只有取两个值,表示成功的值的概率为p,那么...
