Description

We need to implement the projection for survival models at some point. The actual implementation needs some thinking and is likely to depend on how the survival models are/will be handled in rstanarm (issue https://github.com/stan-dev/rstanarm/issues/69) and in package survival. But this is mainly related to how this appears to the user. Regarding the projection itself, there should not be too many difficulties provided the likelihood is log-concave.

Research direction

Start by reading the linked rstanarm issue 69 and reviewing how survival models are handled in the survival package. Then trace the project's existing projection entry points and determine the user-facing behavior needed for survival models, including whether the log-concave likelihood assumption applies; done means the expected scope and integration path are documented.
