We clarify that the correlation coefficient in the long-term distribution can be estimated from the phase difference with other wave induced stress when the response amplitude function of the dominant wave induced stress become the largest value. (2) The correlation coefficient of the long-term ...
aThrough the correlation coefficient matrix of variables, we can see a strong link among the indexes selected. Meanwhile, the SPSS output results show that from the KMO and Bartlett, KMO inspection sphericity in 0.685, can mean value for principal component analysis. 通过可变物相关系数矩阵,我们能...

What is correlation? Correlation coefficient is used in statistics to measure how strong a relationship is between two variables. There are several types of correlation coefficients (e.g. Pearson, Kendall, Spearman), but the most commonly used is the Pearson’s correlation coefficient. This coeffici...
