It is necessary to know what monotonic function is to understand Spearman correlation coefficient. A monotonic function is one that either never decreases or never increases as it is an independent variable increase. A monotonic function can be explained using the image below:...
Interpreting Spearman’s Correlation Coefficient Spearman’s correlation coefficients range from -1 to +1. The sign of the coefficient indicates whether it is a positive or negative monotonic relationship. A positive correlation means that as one variable increases, the other variable also tends to in...
The choice between Pearson's and Spearman's correlation coefficients can be thought of as being approximately equivalent to choosing between the median/IQR and the mean/standard deviation as explained in Chapter 1. In the same manner as the median and IQR, Spearman's rank correlation coefficient ...
then you can be pretty confident that the outliers are not influencing the results. You can also calculate the Spearman’s rank coefficient. If this is pretty similar to Pearson’s correlation coefficient, this is also a good indicator that the outliers ...

Firstly, the Spearman rank correlation between all pairs of wind speed series is calculated according to(13). A Spearman rankcorrelation matrixis obtained in the same way as aPearson'scorrelation matrix was obtained when using method I previously explained. ...
