Dear list members, When trying to fit this example from the CRAN repository fro brms, I got the following error message after the 4th chain. I am using R 3.6.1 in Catalina MacOS.
library(brms) group <- rep(c("treat", "placebo"), each = 30) symptom_post <- c(rnorm(30, mean = 1, sd = 2), rnorm(30, mean = 0, sd = 1)) dat1 <- data.frame(group, symptom_post) fit1 <- brm(bf(symptom_post ~ group, sigma ~ group), data = dat1, family = gaussian()) [1] "Error in sampler$call_sampler(args_list[[i]]) : " [2] " c++ exception (unknown reason)" error occurred during calling the sampler; sampling not done I think is a problem with Catalina MacOS, but I don´t know how to solve it.
