If nothing, you should do corr = round (cor (test3)^2,3). @AnalyticsTeam, cor (by default) gives you Pearson correlation coefficient ( r ). If you square that, you get R². Witryna11 sie 2024 · We can determine the correlation coefficient by dividing the covariance of the variables using their standard deviations. Once the formula has returned the correlation coefficient, r, the relationship can be determined. The PPMC formula returns a value between -1 and 1. The higher the number, the stronger the relationship.
