abstract: Performs tuning of clustering models, methods and algorithms including the
  problem of determining an appropriate number of clusters. Validation of cluster
  analysis results is performed via quadratic scoring using resampling methods, as
  in Coraggio, L. and Coretto, P. (2023) <https://doi.org/10.1016/j.jmva.2023.105181>.
