Use a model's fitted distribution to simulate additional data with similar
behaviour to the response. This is a tidy implementation of
`\link[stats]{simulate}`

.

# S3 method for mdl_df generate(x, new_data = NULL, h = NULL, times = 1, seed = NULL, ...) # S3 method for mdl_ts generate(x, new_data = NULL, h = NULL, times = 1, seed = NULL, ...)

x | A mable. |
---|---|

new_data | The data to be generated (time index and exogenous regressors) |

h | The simulation horizon (can be used instead of |

times | The number of replications. |

seed | The seed for the random generation from distributions. |

... | Additional arguments for individual simulation methods. |

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 for the simulated paths..
