%description
Various methods for the identification of trend and seasonal components in
time series (TS) are provided. Among them is a data-driven locally
weighted regression approach with automatically selected bandwidth for
equidistant short-memory time series. The approach is a combination /
extension of the algorithms by Feng (2013)
<doi:10.1080/02664763.2012.740626> and Feng, Y., Gries, T., and Fritz, M.
(2020) <doi:10.1080/10485252.2020.1759598> and a brief description of this
new method is provided in the package documentation. Furthermore, the
package allows its users to apply the base model of the Berlin procedure,
version 4.1, as described in Speth (2004)
