posterior_linpred.brmsfit | R Documentation |
Compute posterior draws of the linear predictor, that is draws before applying any link functions or other transformations. Can be performed for the data used to fit the model (posterior predictive checks) or for new data.

formula containing group-level effects to be considered in
the prediction. If |
re.form |
Alias of |

Optional names of response variables. If specified, predictions are performed only for the specified response variables. |

Positive integer indicating how many posterior draws should
be used. If |

An integer vector specifying the posterior draws to be used.
