(passed by |
reestimate |

Other arguments passed to methods |
Details
The models NAIVE
and SNAIVE
have no specific model parameters. Using refit
for one of these models will provide the same estimation results as one would
use fabletools::model(NAIVE(...))
(or fabletools::model(SNAIVE(...))
.
Examples
lung_deaths_male <- as_tsibble(mdeaths)
lung_deaths_female <- as_tsibble(fdeaths)
fit <- lung_deaths_male %>%
model(RW(value ~ drift()))
report(fit)
fit %>%
refit(lung_deaths_female) %>%
report()
