组合函数

In this method, an interim variable is defined by combining one variable of each subsystem. The interim variable is used to construct the sliding-mode function and the total control law can be derived to guarantee the equilibrium point is reachable in finite time. Using LaSalle invariance theorem, it can be proved further that the equilibrium field only includes one equilibrium point and the equilibrium point is asymptotically stable.

该方法将各个子系统的一个变量进行组合定义成一个中间变量，然后从这个中间变量出发构造滑模函数，通过求取总的控制量保证中间变量在有限时间内收敛到平衡点；进一步利用LaSalle不变性原理证明该收敛域内只有一个平衡点且是渐近稳定的。

However, asymmetric Laplace distribution has only 2 parameters and explicit distribution function form, it can fit the data of stock returns well. Consequently it greatly facilitates the calculation of optimal portfolios and the management of financial risk.

非对称拉普拉斯分布有明确的解析表达分布函数，只含有2个参数，能够较好拟合股票收益率分布的尖峰厚尾偏倚特性，给进一步的研究证券投资组合和金融风险管理带来了很大的便利。

The former can be described completely by their marginal distribution, while the latter by copula function linking them.

其中单个金融资产的风险可以完全由它们各自的边缘分布来描述，而由投资组合产生的风险则完全由连接它们的Copula函数来描述。

In this paper, the basic options as a starting point, the approach of assuming the price of the underlying assets comply with the conditions of normal distribution, we discuss the options buyers were portfolio probability and loss function benefits the mathematical expectation of a meaningful result is derived.

本文以基本期权为起点，在假定基本资产期日的价格遵从正态分布的条件下，讨论期权组合的购买者获益的概率及其损益函数的数学期望，并导出一个有意义的结果

Reduced SQP based on orthonormal bases, orthogonal bases and coordinate bases are studied and compared. With the correction item introduced, the null-space move is adjusted and the reduced SQP based on coordinate bases decomposition is improved.●The key problem of steady-state data processing for RTOPT is studied. A new algorithm of simultaneous strategies for data reconciliation and gross error detection is proposed. Here the objective function that is constructed using maximum likelihood principle and joint distribution function is minimized. Efficient algorithm is developed which exploited the nonlinear lease-square structure of this objective function.

仿真结果表明了算法的有效性；●深入研究了在线优化中的一个关键问题——稳态数据处理问题，用基于组合概率分布的目标函数联立求解粗劣误差检测和数据调和问题；以精馏塔在线优化的数据处理和模型修正为例，提出一种根据模型方程对参数的依赖性进行过程模型分解的分层策略，可以将数据调和和参数估计统一在数据处理的大框架中，为进一步的过程性能分析、操作状况评价以及在线优化提供可靠的基准，具有非常重要的工程应用价值；●将优化命题的形式扩展到更通用的形式。

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。

It then invokes NEG and SBB in order to perform a zero test on the result, just as you saw in the previous example.

你应该已经注意到NEG/SBB组合了，这段代码除了加上了一个略有些复杂的函数外，其实是与上面的代码相同的。

It is also possible to define functions with a variable number of arguments.

定义函数的时候可以带若干个参数，有三种可以组合使用的不同形式。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
