Abstract

Romanian Abstract: Aceasta lucrare abordeaza câteva dintre principalele obiective ale analizei trendurilor seriilor de timp discrete. Un aspect major al acestei analize consta in identificarea unui model matematic ce descrie tendinţa persistenta pe termen lung a evoluţiei variabilei studiate. Modelul poate evidenţia câteva caracteristici importante ale tendinţei pe termen lung a seriei de timp. Poate fi, de asemenea, folositor in previziunea viitoarelor valori ale seriei de timp. Un alt aspect important al analizei unui trend consta in detectarea schimbarilor semnificative care au survenit (sau care ar putea surveni in viitor) in tendinţa pe termen lung a unei variabile. English Abstract: This paper approaches some main objectives of the analysis of trends in discrete time series. A major aspect of this analysis is to identify a mathematical model that describes the persistent long-term movement of the studied variable. The model could reveal some important characteristics of the long-term time series pattern. It may also be useful for predicting the time series future values. Another important aspect of a trend analysis is to detect the significant changes that occurred (or that could occur in the future) in the long-term pattern of a variable.
