I. Altman inventively established multi-variable Z-score creditmodel in 1968, credit risk management has changed from classical qualitative analysisto modern quantitative management. There are several models that have beenacknowledged, for example, KMV, Credit Risk Plus, Credit Metrics, Credit PortfolioView Model and so on.

I。 Altman1在 1968 年开创性地建立了多变量的 Z 计分信用模型之后，信贷风险管理就实现了从古典的定性分析向现代定量技术管理理念的飞跃，并由此掀起了对现代信用风险管理量化技术与方法研究的热潮。

In particular, a multivariate t distribution is attained to characterize the prediction information corresponding to HMM mean vector and precision matrix.

It is also necessary to improve the effective integration of quantitative and qualitative data so as to study the optimum strategy and potential impacts on the economy more precisely.

希望在今后的研究中还可以在更加细分谈判标的基础上，建立考察更多变量的动态局部均衡模型，深化应用动态一般均衡模型，对定量和定性数据进行有效融合等改进，从而可以更精确地对最优策略和潜在经济影响进行研究。

Since most of the studies are based on the Hardy space and the Bergman space of the unit disk, there is still a lack of their properties on the higher dimensional region for the reason that the topological boundary of the higher dimensional region is very complicated and the multi-dimensional complex analysis theory is very whimsical, which make it difficult to be extended.

但对于多变量的Toeplitz算子和Hankel算子还有很多基本问题没有解决，对它们的研究也变得更加困难。一个很重要的原因就是高维区域的拓扑边界变得非常复杂以及多元复分析理论在其中的应用也更困难。
