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.
