indicating a perfect positive and negative linear relationship respectively between two variables. The calculation of the correlation coefficient is normally performed by statistical programs, such SPSS and SAS,
Pearson相关系数(Pearson Correlation Coefficient):在R中,我们可以使用cor函数来计算Pearson相关系数。该函数的语法如下: 代码语言:txt 复制 cor(x, y, method = "pearson") 其中,x和y是两个向量或者数据框,method参数设置为"pearson"表示计算Pearson相关系数。 Pearson相关系数衡量了两个变量之间的线性关系程度,取值...

Furthermore, visualizing thedata using a SAS graphs visibly demonstrate the impact of removing questionable data points. Data re-sampling techniques, such as the jackknife, also can be used to determine the true value of a correlation coefficient, and are an alternative to removing data.Eric...
The correlation coefficient is a symmetrical statistic. That is, it simply describes the association between X and Y without worrying about whether Y = f(X) or X = f(Y). It would produce the same result in either case. Unlike the regression coefficient, whose values range from 0.0 to ...

The fusion of multiple networks produces redundant features, which are tuned by employing the Pearson correlation coefficient (PCC)-based optimization technique. The structure of this article is as follows. Details of the proposed technique are described in Section 3. Experimental results to validate ...
The variables with higher correlation with the sulfur distribution coefficient were the content of sulfur in both steel and slag at the end of the refining process, as well as the Si content at that stage of the process. As secondary variables, the Si content and the basicity of the slag ...
