WebSpearman Rank Correlation - Basic Properties. Like we just saw, a Spearman correlation is simply a Pearson correlation computed on ranks instead of data values or categories. This results in the following basic properties: Spearman correlations are always between -1 and +1; Spearman correlations are suitable for all but nominal variables. WebMar 4, 2024 · The Spearman rank correlation coefficient often denotes as ρ (rho) or rs, is the non-parametric version of the Pearson correlation coefficient. It can deal with ordinal, interval or ratio variables for monotonic relationships. As its name suggests, Spearman’s ρ relies on ranks of the given two variables instead of their values.

Classic correspondence analysis is a statistical method that gives a score to every value of two nominal variables. In this way the Pearson correlation coefficient between them is maximized. There exists an equivalent of this method, called grade correspondence analysis, which maximizes Spearman's ρ or Kendall's τ.
