"WebThe simplest way of transforming a numeric variable is to replace its input variables with their ranks (e.g., replacing 1.32, 1.34, 1.22 with 2, 3, 1). The rationale for doing this is to limit the effect of outliers in the analysis. If using R, Q, or Displayr, the code for transformation is rank (x), where x is the name of the original variable.
