亚高斯分布是概率论中的一个概念,主要描述一类随机变量的分布特征。这类随机变量的尾部概率衰减速度快,与经典的高斯分布(Gaussian distribution)相比,表现出更强的尾部衰减性质。亚高斯分布的定义基于随机变量的矩母函数,满足特定条件的随机变量被视为亚高斯分布。文章中还提到了与亚高斯分布相关联的Cherno...

The approach applied to a pair of stock index returns demonstrates that such a bivariate vector can be a sample coming from a bivariate sub-Gaussian distribution. The methods presented here can be applied to any nontrivially distributed financial data, among others....
Here rand is a random number between 0 and 1 chosen with respect to uniform probability distribution. The nearest couplings t1 and t2 are not perturbed. The strength of the perturbations is given relative to the size of the gap, which is given by \(|t_2 - t_1|\). All perturbations ...

Exponential bounds for the distribution of norms of sub-Gaussian random vectors taking its values in R n are found. The random vector X taking its values in R n is called sub-Gaussian with respect to a symmetric positive definite n×n matrix R if for all x∈R n the following inequality...
