Applies a model-specific estimation technique to predict the values of missing values in a tsibble, and replace them.
# S3 method for class 'ARIMA'
interpolate(object, new_data, specials, ...)A model for which forecasts are required.

(passed by fabletools::forecast.mdl_df()).
Other arguments passed to methods
