%description
Methods for decomposing seasonal data: STR (a Seasonal-Trend decomposition
procedure based on Regression) and Robust STR. In some ways, STR is
similar to Ridge Regression and Robust STR can be related to LASSO. They
allow for multiple seasonal components, multiple linear covariates with
constant, flexible and seasonal influence. Seasonal patterns (for both
seasonal components and seasonal covariates) can be fractional and
flexible over time; moreover they can be either strictly periodic or have
a more complex topology. The methods provide confidence intervals for the
estimated components. The methods can be used for forecasting.
