ABC-PRC: Correction posted on PNAS

In connection with our ABC-PMC paper, to appear in Biometrika, the authors of the original ABC-PRC paper have recently published a corrigendum in PNAS that agrees with our analysis of the bias., due to the likelihood ratio approximation based on two unbiased estimators being itself biased. The correction they propose is to modify the denominator in  an importance sampling manner, as in ABC-PMC. So this kind of nicely solves the earlier controversy surrounding those papers!
