Initializing MH algorithm at different parameter values for each chain


I am wondering if it possible to specify different initial parameter values for each chain of the metropolis hasting algorithm in Dynare. For example, suppose I know that one of my posteriors is multimodal and I want to start a chain in one region of the parameter space and a different chain in another region. Is this possible?


No, that is not easily doable. You would need to adjust posterior_sampler_initialization.m to achieve this.
