Updating models fit with brm_multiple


Operating System: Windows 10
Interface Version: brms 2.7.0
Compiler/Toolkit: clang 7.0.1

Can we use update to update models fit to a mice (multiple imputed) data set using brm_multiple? I would like to update with a new mice data set so that brm_multiple is used again to fit each imputed data set and combine the results.

data_mice1 <- mice(data1, m = 5, print = FALSE)
data_mice2 <- mice(data2, m = 5, print = FALSE)

model <- brm_multiple(data_mice1, formula)

updated_model <- update(model, newdata = data_mice2)

Will the updated_model object be the result of calling brm_multiple again using data_mice2?


Good point. This is not yet supported. Would you mind opening an issue for this on https://github.com/paul-buerkner/brms?


Done. Thank you!
