Standard errors after posterior maximization

Estimation ML/Bayesian estimation
1

Hi,
When estimating a model using bayesian methods, I get very high standard errors after the posterior maximization. Is this an indication that the estimates are insignificant and that I should not proceed with posterior simulation? Or how should I interpret this?

Thanks in advance,
Anette

First of all, you should check convergence. How do the trace_plots and the prior/posterior-plots look?
