`R/posterior_predict.R`

`posterior_predict.Rd`

Draw from the posterior predictive distribution of the outcome. See posterior_predict.stanreg() in the rstanarm package for an example.

`posterior_predict(object, ...)`

- object
The object to use.

- ...
Arguments passed to methods. See the methods in the rstanarm package for examples.

`posterior_predict()`

methods should return a \(D\) by \(N\)

matrix, where \(D\) is the number of draws from the posterior predictive distribution and \(N\) is the number of data points being predicted per draw.

The rstanarm package (mc-stan.org/rstanarm) for example methods (CRAN, GitHub).

Guidelines and recommendations for developers of R packages interfacing with Stan and a demonstration getting a simple package working can be found in the vignettes included with rstantools and at mc-stan.org/rstantools/articles.
