Estimates of stability given by the various methods, converted to relative ranks (from 0.00 = most unstable, to 1.00 = most stable) for easiness of comparison between methods.

ID and Name are as in WALS [39]. D is [35]’s , and are [58]’s “all families” and “accepted families only”, W is [59]’s “metric C”, CM, CC and CR are [43]’s “Mantel”, “Coherence” and “Rank” methods, M represents estimates of Maslova’s stability (as implemented by us). We used -D and -CR to ensure that all estimates have the same directionality. The WALS Area is given as Phonology, Morphology, Nominal Categories, Nominal Syntax, Verbal Categories, Word Order, Simple Clauses, Complex Sentences, Lexicon, Sign Languages and Other.
