Titre : Computerized matching of relevés and association tables, with an application to the British National Vegetation Classification Type de document : Livre Auteurs : M. O. Hill, Auteur Année de publication : 1989 Article en page(s) : pp. 187-194 Langues : Anglais Mots-clés : Bayesian inference diagnose Goodness-of-fit Résumé : "When a new relevé is to be assigned to a pre-existing type, its composition is compared with an association table. Bayesian inference may seem a good way to make the comparison, but presents difficulties. In an alternative approach, three indices of goodness-of-fit are proposed. Compositional satisfaction is a measure of how well the species composition of the relevé fits the constancy classes in the table; it is a minor modification of the Czekanowski coefficient of similarity between observed and expected numbers of species in each constancy class. Dominance satisfaction is a modification of the Czekanowski similarity between the relevé and cover values that might be expected from the association table. Dominance constancy is a weighted mean of the constancy class of the four most abundant species in the relevé. A computer program, TABLEFIT, combines them into a single index. It has been tested on British mire vegetation."
