| Popis: | Change-points are present in many environmental time series. Time variations in environmental data are complex and they can hinder the identi - cation of the so-called change-points when traditional models are applied to this type of problems. In this study, it is proposed an alternative approach for the application of the change-point analysis by taking into account this data structure (seasonality and autocorrelation) based on the Schwarz Information Criterion (SIC). The approach was applied to time series of surface water quality variables measured at eight monitoring sites. Fundação para a Ciência e a Tecnologia (FCT) |
