generate.stl_decomposition: Generate block bootstrapped series from an STL decomposition

In feasts: Feature Extraction and Statistics for Time Series

Generate block bootstrapped series from an STL decomposition

Description

Produces new data with the same structure by resampling the residuals using a block bootstrap procedure. This method can only generate within sample, and any generated data out of the trained sample will produce NA simulations.

Usage

## S3 method for class 'stl_decomposition'
generate(x, new_data, specials = NULL, ...)

Arguments

x	A fitted model.
new_data	A tsibble containing future information used to forecast.
specials	(passed by fabletools::forecast.mdl_df()).
...	Additional arguments for forecast model methods.

Examples

as_tsibble(USAccDeaths) %>%
  model(STL(log(value))) %>%
  generate(as_tsibble(USAccDeaths), times = 3)
