Compute Kendall's W, also known as coefficient of concordance among observed rankings and those predicted by the Plackett-Luce model.
kendallW(x, ...)# S3 method for default
kendallW(x, y, ...)
# S3 method for pltree
kendallW(x, newdata = NULL, ...)
Kendall's W (coefficient of concordance)
an object of class pltree
additional arguments passed to methods
an object of class pltree
data for predictions

It is as wrapper of the function DescTools::KendallW, adapted to compute the Kendall's W on the observed and predicted rankings.
Kendall's W values range between 0 (no agreement) to 1 (full agreement)
