%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 and in more detail in
Schulz (2026) <doi:10.32614/RJ-2026-025>. Furthermore, the package allows
its users to apply the base model of the Berlin procedure, version 4.1, as
described in Speth (2004)
