代码说明:

应用背景在假设检验中,通常要检查2个元素是否在同一分布中采样。在直方图的情况下,有没有直接和具体的方式来做它。本代码由本韦尔奇的测试实现了仓和Fisher组合概率法加入最后的P值。关键技术此代码简单地实现来自统计的声音和强大的结果。韦尔奇的测试是用来检查是否有2个人口可能有相同的意思,同时考虑到方差和数量的样本(可能不同),从每一个集。通过样本数的方差对均值的均值进行加权。这可能是有用的比较组的直方图,也考虑到不确定性。斌斌比较然后用Fisher方法使每个韦尔奇的测试作为一个卡方检验的自由度下完成2K的p值,其中K是箱的数目。的代码的最终输出的概率,给出的零假设,我们在稍微不同的条件下观察相同的图像,得到的样品,我们输入的算法。

    we investigate a new blind adaptive fractionally-spaced TEQ (FS-TEQ) for multicarrier systems in order to reduce efficiently intersymbol interference. We also exploit the cyclic prefix and fractionally-spaced TEQ to create a blind adaptive globally convergent channel-shortening algorithm.

    matlab Coastal Land Use/Land Cover maps and Coastal Regulation Zone map on 1:25,000 and 1:50,000 scales derived from satellite data were collected from State Coastal Zone Management Authorities and enlarged into 1:12,500 scale. The georeferenced maps were digitized in ARC-INFO GIS. Digitized maps were edited, labeled and a layout was prepared. The area statistics of different Ecologically Important Areas were generated and presented in the maps.
