%description
Provides a collection of commonly used univariate and multivariate time
series forecasting models including automatically selected exponential
smoothing (ETS) and autoregressive integrated moving average (ARIMA)
models. These models work within the 'fable' framework provided by the
'fabletools' package, which provides the tools to evaluate, visualise, and
combine models in a workflow consistent with the tidyverse.
