| Tiivistelmä: | Environmental data are obtained often by passively monitoring variables over long time periods. Therefore, time series often resemble those obtained in other areas /socio-economic and business studies/ where passive monitoring is the normal approach. A unified, fully recursive approach to modelling, forecasting and seasonal adjustment of non-stationary time series is presented, and used as a flexible tool in the analysis of environmental data. It is based on time-variable parameter /TVP/ versions of various time-series models and exploits recursive filtering and fixed interval smoothing algorithms in the microCAPTAIN computer program. A practical example is presented, for the demonstration of COÜV2ÜV analysis. |
