generate.stl_decomposition {feasts}

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 the time points and exogenous regressors to produce forecasts for.

specials

(passed by fabletools::forecast.mdl_df()).

...
