%description
Functions implementing Single Source of Error state space models for
purposes of time series analysis and forecasting. The package includes
ADAM (Svetunkov, 2023, <https://openforecast.org/adam/>), Exponential
Smoothing (Hyndman et al., 2008, <doi: 10.1007/978-3-540-71918-2>), SARIMA
(Svetunkov & Boylan, 2019 <doi: 10.1080/00207543.2019.1600764>), Complex
Exponential Smoothing (Svetunkov & Kourentzes, 2018, <doi:
10.13140/RG.2.2.24986.29123>), Simple Moving Average (Svetunkov &
Petropoulos, 2018 <doi: 10.1080/00207543.2017.1380326>) and several
simulation functions. It also allows dealing with intermittent demand
based on the iETS framework (Svetunkov & Boylan, 2019, <doi:
10.13140/RG.2.2.35897.06242>).
