Sample from a Bayesian Regression Model — brms

This samples from the posterior predictive for each component in a multiresponse Bayesian Regression model.

Usage

brms_sampler(fits, newdata = NULL, indices = NULL, ...)

Arguments

fits: The fitted 'BRMS' model model from which to draw samples.
newdata: A data.frame containing new inputs from which to sample responses. If NULL, defaults to the data used to estimate fit.
indices: The coordinates of the response from which we want to sample.
...: Additional arguments to pass to posterior_predict in the 'brms' package.

Value

A data.frame containing a single posterior predictive sample at each of the newdata rows passed into a fitted BRMS model. Each column corresponds to one outcome variable, each row to the associated row in the newdata input..
