%description
Methods for decomposing seasonal data: STR (a Seasonal-Trend time series
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 also be used for forecasting.
