update.Arima | R Documentation |
There seems to be no function in package forecast (as of version
8.2) to re-estimate an ARIMA model on a subset of the original time series.
This update
method does exactly that.
## S3 method for class 'Arima'
update(object, subset, ...)
object |
an object of class |
subset |
an integer vector selecting part of the original time series (and external regressors). |
... |
further arguments to be passed to |
the updated model.
