%description
The nonparametric trend and its derivatives in equidistant time series
(TS) with short-memory stationary errors can be estimated. The estimation
is conducted via local polynomial regression using an automatically
selected bandwidth obtained by a built-in iterative plug-in algorithm or a
bandwidth fixed by the user. A Nadaraya-Watson kernel smoother is also
built-in as a comparison. With version 1.1.0, a linearity test for the
trend function, forecasting methods and backtesting approaches are
implemented as well. The smoothing methods of the package are described in
Feng, Y., Gries, T., and Fritz, M. (2020)
<doi:10.1080/10485252.2020.1759598>.
