Reviews: Predictive Approximate Bayesian Computation via Saddle Points

I am happy with all of your responses, though slightly confused over Q2 (rev2). One can't draw samples from improper priors in the first place, and other techniques (such as Rodrigues et al) won't save you there. You simply need to draw your samples from a distribution that is not the prior. I am still positively inclined towards this paper, and following the response and comparison to EP-ABC I will increase my score to 7 (from 6). Of course when the prior is improper or merely diffuse with respect to the posterior this will be impossible or at best highly inefficient.
