Bayesian inference: the Gelman-Rubin value

UQ with UQLab Community Q&A and How To
1

Dear Prof,
When using Bayesian inference to calibrate model parameters, AIES method is adopted. By adjusting the a value, it is difficult for the Gelman-Rubin value to be less than 1.1 and greater than 1.0. It’s always between 2 and 3, so what can I do?
