Approximate Bayesian Computation (ABC) is a useful framework for conducting inference when likelihood functions are computationally infeasible or unknown. Common ABC procedures require assumptions of independence or exchangeability to generate high-quality inference. In this work, we consider the use of distance-based ABC methods, based on U-statistics, that can feasibly be used when data are dependent. We show a consistency result regarding such procedures and demonstrate their usefulness on some example time-series experiments.
