Table 4 Average values of each evaluator of the initial classification and that obtained with each assignment rule. Averages were calculated across the different number of groups 2 to 18 in B. hyrcana (section A) and 2 to 17 in T. baccata (section B) datasets, before (not underlined) and after (underlined) correcting for the ratio of “statistically valid” Appendix 3 groups. Ranks (1 to 10) are calculated from the corrected averages (i.e., from italicized values). Incidence-based evaluators are specified in the table with braces

From: The assignment of relevés to pre-existing vegetation units: a comparison of approaches using species fidelity
