A note on the ABC-PRC algorithm of Sissons et al. (2007)

TL;DR

This paper tests the ABC-PRC algorithm from Sissons et al. (2007) and shows through a toy example that it fails to converge to the true posterior distribution.

Contribution

It provides an empirical evaluation of the ABC-PRC algorithm and demonstrates its non-convergence in a simple example.

Findings

ABC-PRC does not converge to the true posterior in tested scenarios

The paper highlights limitations of the ABC-PRC algorithm

Empirical evidence questions the reliability of ABC-PRC for accurate inference

Abstract

This note describes the results of some tests of the ABC-PRC algorithm of Sissons et al. (PNAS, 2007), and demonstrates with a toy example that the method does not converge on the true posterior distribution.
