Please also provide the following information in addition to your question:
- Operating System: MacOS 10.14.5
- brms Version: 2.9.0
In the tutorial “Advanced Bayesian Multilevel Modeling with the R Package brms,” there is a formula
fit_zinb2 <- brm(bf(count ~ persons + child + camper, zi ~ child), data = zinb, family = zero_inflated_poisson())
How would one run
zi ~ child?
I’ve tried other arguments like
marginal_effects(fit_zinb2, re_formula = zi ~ child), and
marginal_effects(fit_zinb2, resp = "zi") (based on this answer) which made no difference.
