Description
In multivariate models such as:
brm(mvbind(y1, y2, y3) ~ x1 + x2 + (1 |id| grp), data = data, family = family())
Projpred crashes with the error: Unexpected number of
| characters in group terms. Please notify the package maintainer.
Running it without the <id>
works currently.
What would you advise ?
