The built-in model set for get_cv and get_fcast:
a naive random walk, ETS, Theta and ARIMA, each fitted on
log(observation) to stabilise count variance (fable
back-transforms automatically).
Extend rather than replace by composing, e.g.
c(default_models(), list(CUSTOM = fable::ARIMA(observation))).
Value
A named list of fable model definitions.
Examples
default_models()
#> $NAIVE
#> <RW model definition>
#>
#> $ETS
#> <ETS model definition>
#>
#> $THETA
#> <theta model definition>
#>
#> $ARIMA
#> <ARIMA model definition>
#>
