查询词典 correlation matrix

After explaining correlation theory and its important features, the rescaled range analysis、modified rescaled range analysis and detrended fluctuation analysis are analysed. As for the drawbacks produced by the rescaled range analysis when faced with short term correlation, a modified rescaled range analysis based on short term correlation model is applied to Shanghai stock market and Shenzhen stock market. The result is explained and compared.

车体装焊的复杂性决定了误差产生的多因素性，车体制造过程中产生误差的工位和主要因素是不断变化的，采用相关性分析方法从众多的误差根源中准确地发现最主要的误差源；结合工程实践，论述了车体尺寸波动的相关性分析方法的原理，根据测量点的相关性分析和车体焊接工艺的层次结构，可准确地找到产生车体尺寸误差的工位；讨论了如何利用相关系数矩阵的特征值和相应的特征向量判断尺寸波动的模式，指出测量数据的波动主要按最大特征值所对应的特征向量方式波动，引起这种波动的原因是车体误差产生的主要原因，应重点采取措施加以控制；提出了应用计算机进行相关性分析的解决方案。

There exists a positive correlation in the analysis of the relationship between the students" proficiency test of self-explanation and academic performances in the correlation reaearch of the students" proficiency test of self-explanation and academic performances: there is a close relationship between academic performances of students and the mastery level of chemical concept study. As for the students with higher level of self-explanation,their quality of learning is higher and their academic performances are relatively better, proving that there is a close positive correlation between the academic performance of the test subjects and their self-explanation ability.

The invention relates to a node marking method in a wireless Mesh network, including that a first node transmits connection request information; a second node returns to connection response information or selects an undistributed correlation sign to mark the connection relation and return to one connection response information; the first node judges whether the correlation sign is conflicted with a distributed correlation sign or not, if yes, then retransmitting is carried out; the first node or the second node transmits information to a correspondent node; the correspondent node searches a corresponding transmitting node from a local record according to the analyzed MAC address and searches a Mesh node mark; by judging according to the mark, if no bit position is corresponding to the Mesh node mark or the corresponding bit position is set as 'no', which means that no data is transmitted to the correspondent node; otherwise, data is transmitted to the correspondent node.

本发明涉及无线Mesh网络中的节点标识方法，包括第一节点发送连接请求消息；第二节点返回连接响应消息，或者选择一个未分配的关联标志来标识连接关系，返回一个连接响应消息，第一节点判断关联标志与已分配的关联标志是否冲突，如是则重新发送；第一或第二节点向对端节点发送消息；对端节点根据解析出的MAC地址从本地记录中查找对应的发送节点，并查找Mesh节点标识；根据标识进行判断，若没有与Mesh节点标识对应的比特位或对应的比特位设置为&否&，则表示没有要发送给对端节点的数据；否则表示有。
