查询词典 multivariate distribution

If there exist a family of copulas, we could construct any bivariate or multivariate distribution functions of given margins by Sklars theorem and these distributions are always very useful for simulation.

如果我们有一族copula，那么根据Sklar定理，可以构造出任何指定边缘分布的二元或多元联合分布函数，而这些分布函数在建模与模拟方面是非常有用的。

第三章和第四章由经验分布函数出发，利用B—样条函数理论，分别给出构造一元分布函数和多元分布函数的方法。

Copulas are functions that join multivariate distribution functions to their one-dimensional marginal distribution functions.

Copula函数是将多维随机变量的联合分布和其边缘分布连接起来的一种函数。

Copulas are functions that joint multivariate distribution functions to their one–dimensional marginal distribution functions.

Copula用来描述多元随机变量的一维边缘分布与其联合分布之间的函数关系。

The relations between multivariate Poisson distribution and multinomial distribution or multivariate normal distribution are given.

最后给出了多元Poisson分布与多项分布以及多元正态分布之间的关系。

The major characteristic of the new method is that it computes the portfolio's VaR by using the functions of copula and marginal distributions only, and don't need to confirm the expression of the multivariate distribution.

其主要特点是只需要考虑连接函数与边际分布，就可以计算投资组合的在险价值，而不需要确定联合分布的具体形式。

Not only the non-linear dependence between financial markets is able to be caught, but also the more flexible multivariate distribution which can be use to analyze portfolio VaR is able to be obtained from this model.

该模型不仅能够得到金融市场间的非线性相关性，而且可以得到更灵活的多元分布，进而用于资产投资组合VaR分析。

We first denoise the SAR image by Lee filter.Next,the maximum likelihood classifier based on different distribution was used for SAR and SPOT images(Based on Wishart distribution and multivariate Gaussian distribution respectively),to extract the conditional probability of each pixel for each class.

首先使用李式滤波器滤除全偏极雷达数据噪声，接下来同样是使用采用最大似然法来分类融合影像，(不同的在于全偏极雷达影像使用Wishart几率分布，在光学影像采用multivariate Gaussian几率分布)将每个类别中每个像元属于某个类别的几率值计算出来，再利用Dempster-Shafer evidence theory来结合这些类别的机率值。

But when a rectangular continuous data set appears to have a longer tailed than normal distribution or it contains some values that are influential on statistical inference with normal distribution, the multivariate t distribution becomes useful for multiple imputations as an alternative to the multivariate normal distribution.

在多重插补法的基础上，当一个矩形连续数据集看起来有一个比正态分布还长的尾巴，或者是它包含了一些对正态分布的统计推断有影响的数据，多元t分布作为多元正态分布的替代分布，对于多重插补来说变的很有用了。
