%description
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)
<doi:10.1016/j.jmva.2023.105181>.
