Hi, I was wondering what is the current status of ABC samplers in Julia.

I have seen that GpABC.jl has a few options, but I was wondering if there are alternative packages with a special focus on SMC. I do not have something specific in mind, but I am currently exploring the available options - perhaps something like this but implemented within an active package.

ABC is a misnomer IMHO. It’s just bayesian models using summary statistics as observations. So yes. Basically you run your forward model, calculate your summary statistics, and then

In principle and for the simplest cases it is. How would you implement it with Turing? Also, do you know whether SMC is currently supported in that package?

I implemented some ABC-SMC methods a while ago here, but I never found the time to clean it up further and make better use of the ecosystem (e.g. Turing).
