Only in cauchy distribution are expected value and variance non-exist. By sas programming with SQL and MACRO we solve the fit of frequency distributions of data with these distributions. Meanwhile good-of-fit test is actualized so that the bound of parameters of distribution function is dwindling until the desired accuracy is arrived. The process is executed by the circle of macro.

利用SAS的SQL和MACRO等语句编写了大量的程序，以拟合优度检验结果为标准，不断地变换八种分布的参数变化范围，通过宏程序的不断循环，逐步缩小参数的范围，最后达到预先设定的标准，从而可以发现八种分布中哪几种分布能比较好地拟合给定的实际频数资料，我们再根据拟合优度检验的结果判断出哪种分布拟合实际频数资料最好，最终获得该频数资料的最佳的理论分布函数形式。

In this paper,we use the historical data to get the experiential distribution function of conditional revenue ratio when we can not determine the type of the allied distribution of the price and revenue ratio,and then we calculate the VaR under a certain price level of the price.

1研究意义VaR是目前证券投资风险管理的重要工具，在数学上，表示为投资组合收益率分布的下α分位数，表达式为：P=α(VaR 0)图1 VaR的图形表示其中，ΔP表示在Δt时间内，某个金融资产的市场价值的变化，α为给定的概率，如图1所示。

This regression problem is dicult for several reasons: large number of examples, large number variables (most of which are discrete and multi-valued), non-stationarity of the distribution, and a conditional distribution of the dependent variable which is very dierent from those usually encountered in typical applications of machine learning and function approximation.

这个回归问题是，邸邪教组织有多少个原因：大量的例子，大批变量（其中大部分是离散和多值），非平稳性的分布，以及有条件的分布因变量，这是非常邸erent从这些一般遇到的典型应用机器学习和函数逼近。

This paper discusses whether the definitions of heavy-tailed distribution s produced by slow-varying function and the definitions of heavy-tailed distribution s produced by exponential echelon matrix are congruous.

It make a formally unification between discrete distribution and continuous distribution at the definition of failure rate function.

四。借助广义δ函数，首次提出了离散型分布失效率函数的一种新的定义，这种定义使离散型分布与连续型分布的失效率函数定义在形式上得到统一，这种形式上的统一使得离散型寿命分布中各特征函数之间的关系与连续型寿命分布中各特征函数之间的关系完全相同。

A result that may be useful for part II is that if X is a continuous random variable taking positive values with cumulative distribution function F and Rn is the range of a sample of size n taken from this distribution, then
