In all the following tables we show for each represented syntaxonomical association the following quantities:

    • Clust.: Number of PCM clusters created to reproduce the association of its subassociations.
    • Rel.: Number of relevés available from the database.
    • Typ.: Number of relevés used in the typical (training) set.
    • Trans.: Number of relevés in the transitional set.
    • 1º sens.: Sensitivity of the classifier taking into account the first choice of the classifier.
    • 2º sens.: Sensitivity of the classifier taking into account the first and second choices of the classifier.
    • PPP: Positive predictive power of the classifier.
