generate.model_mean: Generate new data from a fable model

Description

Simulates future paths from a dataset using a fitted model. Innovations are sampled by the model's assumed error distribution. If bootstrap is TRUE, innovations will be sampled from the model's residuals. If new_data contains the .innov column, those values will be treated as innovations.

Usage

# S3 method for model_mean
generate(x, new_data, bootstrap = FALSE, ...)

Arguments

x

A fitted model.

new_data

A tsibble containing the time points and exogenous regressors to produce forecasts for.

bootstrap

If TRUE, then forecast distributions are computed using simulation with resampled errors.
