Dear R-Help,

1. Does somebody know a diagnostic tool to determine the n(s), smoothing
parameter of the seasonal component in the STL method for Time Series?
s.window= n(s)= smoothing parameter
Is tsdiag the solution? If yes how can it be used? Should I use arima or

2. Also does the STL method take n(p), the number of observations in
each cycle of the seasonal component, automatically from the FREQUENCY
of the ts (Timeseries) object?

Thanks a lot,
