  Such low values indicate that the effective sample size estimators may be biased high and actual performance may be substantially lower than quoted.
  -The following parameters had split R-hat less than 1.1:
  +The following parameters had split R-hat greater than 1.1:
  mu[1], mu[2], theta
  Such high values indicate incomplete mixing and biasedestimation. You should consider regularization your model with additional prior information or looking for a more effective parameterization.
