Hi Solomon:
This was my model:
m2<-brm(Response ~1+Avglength,
data = sdf1,
family = cumulative(link=“probit”, threshold=“flexible”),
prior = c(prior(normal(0,2), class=Intercept),
prior(normal(0,10), class=b)),
chains=2,
iter=1000,
init_r=2)
where Response has satisfaction level from 0 to 10 and Avglength is the size of fish individual angler caught. Error are below:
Chain 1: Stan can’t start sampling from this initial value.
Chain 1:
Chain 1: Initialization between (-2, 2) failed after 100 attempts.
Chain 1: Try specifying initial values, reducing ranges of constrained values, or reparameterizing the model.
[1] “Error in sampler$call_sampler(args_list[[i]]) : Initialization failed.”
[1] “error occurred during calling the sampler; sampling not done”
