I have created a hierarchical model that can be scaled in dimensions. Since there are multiple combinations of the right sets of parameters I tend to archive better results with NUTS sampler instead of SMC. (example below) For Model Selection I want to use the Bayes Factor. I know that the marginal…

You can try bridge sampling (i have discussed with @Olaf in Fix Bridge sampling for variables with shape>1?).
