Refit a MEAN model

Applies a fitted average method model to a new dataset.

# S3 method for model_mean
refit(object, new_data, specials = NULL, reestimate = FALSE, ...)

Arguments

object	The time series model used to produce the forecasts
new_data	A tsibble containing future information used to forecast.
specials	(passed by fabletools::forecast.mdl_df()).
reestimate	If TRUE, the mean for the fitted model will be re-estimated to suit the new data.
...	Additional arguments for forecast model methods.

Examples

lung_deaths_male <- as_tsibble(mdeaths)
lung_deaths_female <- as_tsibble(fdeaths)

fit <- lung_deaths_male %>%
  model(MEAN(value))

report(fit)
#> Series: value 
#> Model: MEAN 
#> 
#> Mean: 1495.9444 
#> sigma^2: 187619.7152 

fit %>%
  refit(lung_deaths_female) %>%
  report()
#> Series: value 
#> Model: MEAN 
#> 
#> Mean: 1495.9444 
#> sigma^2: 32299.2909
