It appears that every invocation of posterior_linpred and posterior_epred gives a different permutation of the draws. This prevents users from doing posterior calculations (e.g. covariances) using the draws. Relatedly, I was unable to find an example of using the XZ argument to manually compute th…

Keeping the draw order consistent with `posterior_linpred` and `posterior_epred`

brms is more flexible and extensible than rstanarm, and people are building packages on top of brms, see Flocker: an R package for occupancy modeling with `brms` - #8 by Ven_Popov
