简介：在这份报纸，一个统一方法为重申的对数(LIL)和功能的LIL(FLIL)的法律基于更新过程(RP)的强壮的近似(SA)被开发，它确定在在数字、功能的形式的RP的吝啬的价值附近的增加的可变性的asymptotic率的大小分别地。为GI/G/1队列，方法为四个性能函数为LIL和FLIL限制提供完全的分析：队列长度，工作量，忙时间和闲散时间处理，盖住交通紧张划分的三政体。

简介：当处理回归分析时，heteroscedasticity是作者不得不面对的一个问题。特别如果很少信息都不能预先被得到，heteroscedasticity的察觉以及统计模型的评价能是甚至更困难的。到这个目的，这份报纸建议能有效地估计heteroscedastic功能的一个quantile差别方法(QDM)。这个方法，从吝啬的回归的评价是完全自由的工作，简单、柔韧、容易实现。而且，没有任何限制，QDM方法在错误术语启用heteroscedasticity的察觉，因而是广泛地适用。值得提及的，基于建议途径评估者是那两个都，吝啬的回归功能和heteroscedastic功能能被获得。最后，作者进行一些模拟检验建议方法的表演并且使用一个真实数据做一幅插图。

简介：本文重点探讨了从信息活动的性质和方式的角度对系统所作的分类问题,文章依据信息活动的等级把系统分为9类;依据信息演化方式把系统分为4类;依据系统选择信息模式的概率特征对随机性系统和决定性系统,以及二者间的关系进行了分析,并相应给出了系统内在随机性和决定性、绝对随机性和决定性的信息量判据.文章还在对某些关于系统分类的差异观点的比较性研究的基础上,依据现代科学中的相关成果,提出了关于开放系统分类的一些独到见解.
