Correlation coefficient mean
WebYes, the correlation coefficient measures two things, form and direction. If you have two lines that are both positive and perfectly linear, then they would both have the same correlation coefficient. The only way the … WebDefinition [ edit] The form of the concordance correlation coefficient as [1] where and are the means for the two variables and and are the corresponding variances. is the correlation coefficient between the two variables. When the concordance correlation coefficient is computed on a -length data set (i.e., paired data values , for ), the form is.
