Thanks for your response. It is much appreciated.

  • Intercepts only works just fine.
  • I’ll try the univariate models, as you suggest.
  • Regarding init_r = 0.1. Yes, I read online that if it has trouble starting, use inits = 0 or init_r = 0.1. Model with many (correlated) varying-slopes: Sampling not done. Although to be honest, I’m not 100% sure how this impacts things more generally. Hence, I cannot answer your question regarding initialization fails. Which cases are you referring to?

Thanks again.
