查询词典 exist

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。

Yet we have to admit we cannot demonstrate its truth beyond all possible cavil and , further , we have to recognize that the communication which we have with other persons may be less complete than we imagine , but in spite of all this , we feel that it is more than a reasonable assumption - it is a practical certainty - that other persons exist and that we are able to communicate our thoughts to them

但是，我们必得承认，对此真实现象的证明不可能达到无懈可击，而且我们还需要进一步了解，我们跟他人的交谈，可能不像我们想象的那么完备，可是，尽管有这些顾虑，我们对于他人的存在，以及我们能够把自己的思想传达给他人之类的认定，觉得已经超出合乎常理的假定？？
