Seasonal Decomposition and Forecasting, Part I

(Index: www.stat.auckland.ac.nz/~wild/wildaboutstatistics/ ) How big is the seasonal effect? We’ll discuss two models for decomposing a basic time series plot by separating out the trend, seasonal effect and residuals. After you’ve watched this video, you should be able to answer these questions •What is the basic idea behind an additive model (or additive seasonal decomposition)? •Why do we want to find stable structures in our time series?
