decomposition_model

This function allows you to specify a decomposition combination model using
any additive decomposition. It works by first decomposing the data using the
decomposition method provided to <code>dcmp_fn</code> with the given formula. Secondary
models are used to fit each of the components from the resulting
decomposition. These models are specified after the decomposition formula.
All non-seasonal decomposition components must be specified, and any
unspecified seasonal components will be forecasted using seasonal naive.
These component models will be combined according to the decomposition
method, giving a combination model for the response of the decomposition.

Provides tools, helpers and data structures for
developing models and time series functions for 'fable' and extension
packages. These tools support a consistent and tidy interface for time
series modelling and analysis.
