简介:这份报纸为基于F统计数值在高维的部分线性的模型测试回归系数建议一个测试过程。在部分线性的模型,作者首先由一些nonparametric方法估计未知非线性的部件然后概括F统计数值在一些常规条件下面测试回归系数。在这个过程期间,非线性的部件的评价带许多挑战探索概括F-test的性质。作者在更一般的盒子中获得概括F-test的一些asymptotic性质,包括asymptotic规度和有p/n的这测试的力量(0,1)没有规度假设。asymptotic结果是一般的,由增加一些限制条件,我们能在高维的线性模型获得类似的结论。通过模拟研究,作者与理论结果比较表明建议测试的好有限样品的性能。我们的方法的实际用途被一个真实数据例子说明。

简介:在最近的年里,电子learning系统在许多公司作为一个训练工具被采用了,当它能帮助雇员到在一短时间并且以低成本的完全的训练。在这上下文以内,自从2003,在台湾的经济事情(MOEA)的部的工业开发局(IDB)每年赞助了超过50家企业帮助他们实现设定的电子learning系统。关于电子learning的过去的研究主要集中了于一个标准并且采用了回归途径,例如检验在满足或继续的用法意愿和各种各样的先前的因素之间的关系。尽管回归方法能揭开电子learning采纳的重要因素,他们不能显示出每个因素的罐头(weighting),并且因此,公司不能分配资源的最佳的层次。克服这个问题,这研究收集了与从文学和专家意见的评论实现设定的电子learning系统的公司有关的因素,然后构造了一张层次因素桌子。基于因素的适当和独立,并且是由IDB,电子learning方案供应商和IDB的工程领导人的工程提升办公室的专家估计了赞助企业,这篇论文然后设计了一个分析层次过程(AHP)格式问询表并且送了它给这些一样的专家收集他们的回答。因素weightings基于模糊分析层次过程(FAHP)方法被导出。最后,关键因素的分析被执行,建议提供了。基于这个工作的结果,有有限资源的服务工业公司能完成合适的资源分配并且更快速并且成功地采用设定的电子Learning系统。
