查询词典 copula

In the Karakhanid literature■rin■ tended to disappear and its function was partly expressed by the gerundive form turur"there is/ are, to be, la/are"of the verb tur-"stand, stay", which in turn existed in parallel with the copula ol" There is/are, is/are".

The innovations of this paper are as follows:First, the paper has realized to study on the dependence relations between random variables based on copulas, an instrument which is used in this paper as an innovation, in terms of determining the nature and quantification, resorting to the descriptions of dependence properties and association strength and, by way of which, broke through the limitation of study with only depending on independence and linear dependence.

本文的创新点集中体现在三个方面：首先，以Copula为基础，通过对股票市场间的相关关系的强弱描述，从定性和定量两方面来实现对尾部相关性的研究，从而突(来源：7b9bA2bBC论文网www.abclunwen.com)破了目前依赖于独立和线性相关，这仅有的两类相依关系的局限。
