Hi everyone,

For the postierior, the 90% confidence interval looks narrow. Is this a problem? Or it is normal?

Thank you,
Alex

That’s hard to tell. The bands are indeed narrow but not extremely narrow. Are there other warning signs? Like pathological trace plots and convergence diagnostics that suggest non-convergence?
