Pearson cross correlation
The correlation coefficient ranges from −1 to 1. An absolute value of exactly 1 implies that a linear equation describes the relationship between X and Y perfectly, with all data points lying on a line. The correlation sign is determined by the regression slope: a value of +1 implies that all data points lie on a line for which Y increases as X increases, and vice versa for −1. A value of 0 implies th… WebMar 21, 2016 · The Pearson correlation gives you a measure of the degree of linear dependence between two variables. Correlation refers to any of a broad class of statistical relationships involving dependence.From the cross-correlation function you can obtain the correlation coefficient which will give you a single value of similarity.
