I am trying to impute missing data during model fitting similar to the vignette, but running in to a stan error when I try to use weibull()
For example, using the vignette’s data set, this runs properly:
data("nhanes", package = "mice")
bform <- bf(bmi | mi() ~ age * mi(chl), family=gaussian()) +
bf(chl | mi() ~ age, family=gaussian()) + set_rescor(FALSE)
fit_imp2 <- brm(bform, data = nhanes)
While this does not:
bform <- bf(bmi | mi() ~ age * mi(chl), shape ~ age, family=weibull()) +
bf(chl | mi() ~ age, family=gaussian()) + set_rescor(FALSE)
fit_imp3 <- brm(bform, data = nhanes)
Throwing this error:

Any help would be much appreciated. Thanks so much for your time and attention!
