The smooth trend should cope with economic effects without any trouble. Using robust=TRUE in stl makes sense here (and I've changed my original function to do the same). Unless you have more than ten years of data, I would stick with periodic seasonality. It is unlikely to change fast enough to detect with shorter time :// Downloadable! Structural change affects the estimation of economic signals, like the underlying growth rate or the seasonally adjusted series.

At the same time, Kaldor () and Goodwin () developed theoretical nonlinear business cycle models, followed by many others. See Mullineux and Peng () and Granger and Ter¨asvirta (, Sec. ) for recent surveys. Until recently, (economic) time series analysis was dominated by what one might outlier labeling - flag potential outliers for further investigation (i.e., are the potential outliers erroneous data, indicative of an inappropriate distributional model, and so on). outlier accomodation - use robust statistical techniques that will not be unduly affected by ://
The time series material highlights the difference between time-series analysis, which focuses on forecasting, versus cross-sectional analysis, where the focus is typically on model parameters that have economic interpretations. For the time series material, the reader begins with a discussion of random walks, white noise, and :// Downloadable!

Structural change affects the estimation of economic signals, such as the growth rate or the seasonally adjusted series. One important issue that has attracted a great deal of attention in the seasonal adjustment literature is its detection by an expert procedure.

The basic ingredients of the FS are a robust start from an outlier-free subset of observations, a criterion for progressing in the search, which allows the subset to increase by one or more observations at each step, and a set of diagnostic tools that are In Fotopoulos and Ahn (J Time Ser Anal 24(6): –, ), these unit root rank tests were analytically and empirically investigated and compared to the DF test, but with outlier-free processes.
