WebIn comparison to the Pearson correlation coefficient, the Spearman correlation is less to outliers. But at the downside, also about 10% less powerful when measuring a linear trend. Even though, the interpretation of the two correlation coefficient, appears to be similar when considered superficially, they both measure a degree of association. WebThe Spearman rank correlation coefficient, r s, is a nonparametric measure of correlation based on data ranks. It is obtained by ranking the values of the two variables ( X and Y) and calculating the Pearson r p on the resulting ranks, not the data itself. Again, PROC CORR will do all of these actual calculations for you. The Spearman rank ...
