w the nominal threshold of 0.3 which suggests that HMC may have trouble exploring the target distribution.
If possible, try to reparameterize the model.

Effective sample size satisfactory.

The following parameters had split R-hat greater than 1.1:
  y
Such high values indicate incomplete mixing and biased estimation.
You should consider regularizing your model with additional prior information or a more effective parameterization.
