摘要: Six years of rainfall-event pH measurements from the nine-station MAP3S/PCN monitoring network in eastern United States were analyzed. The initial objective was an attempted validation model developed by Eynon and Switzer (1983, Canad. J. Statist. 11, 11–24) on this independent data set. Because some features structure presumed are not evident set, underlying then explored detail. Both aspects investigation confirmed that identification appropriate statistical for such is a difficult undertaking; anticipated may be evident, corresponding to specific stations or exhibit anomalous behavior. Nous avons analyse six annees de mesures se rapportant au pluie, qui ont ete prelevees aux neuf du reseau detection MAP35/PCN l'est des Etats-Unis. Nous avions comme objectif tenter voir si le modele developpe par et La Revue Canadienne Statistique, 11–14) etait valide pour decrire cet ensemble donnees independant. Mais parce que certaines caracteristiques la presumee n'etaient pas apparentes dans donnees, une exploration quelque peu detailles sous-jacente dec done entreprise. Les deux volets l'investigation confirment l'identification d'un statistique approprie telle constitue tâche difficile; anticipee peut ne etre evidente les provenant d'une station particuliere annee peuvent tres bien comporter anomalies.
