Approximate Bayesian Computation (ABC) is typically used when the likelihood is either unavailable or intractable but where data can be simulated under different parameter settings using a forward model. Despite the recent interest in ABC, high-dimensional data and costly simulations still remain a ...
It reviews and develops a class of approximation procedures based upon the idea of ABC, but, specifically maintains the probabilistic structure of the original statistical model. This idea is useful, in that it can facilitate an analysis of the bias of the approximation and the adaptation of esta...
Approximate Bayesian Computation, Class of methods in Bayesian Statistics where the posterior distribution is approximated over a rejection scheme on simulations because the likelihood function is intractable.Different parameters get sampled and simulated. Then a distance function is calculated to measure the...

approximate Bayesian computation, model choice, expected deviance, information criterion, population genetic modelsApproximate Bayesian computation (ABC) is a class of algorithmic methods in Bayesian inference using statistical summaries and computer simulations. ABC has become popular in evolutionary genetics ...
Approximate Bayesian Computation (ABC for short) is a family of computational techniques which offer an almost automated solution in situations where evaluation of the posterior likelihood is computationally prohibitive, or whenever suitable likelihoods are not available. In the present paper, we analyze...
Approximate Bayesian Computation (ABC) is a flexible statistical framework that allows estimating the posterior distribution of a parameter/model through the generation of simulated datasets for cases when there is no close-form of the likelihood of the function24. ABC is widely used in the field ...
Approximate Bayesian Computation for SPD modeling Our ABC approach to SPD modeling builds on recent work by Porčić56, follows standard procedures used in other fields, e.g.,105,106, and involves the following steps: (1) define the prior distributions of the demographic model parameters; (...
In the following article we consider approximate Bayesian computation (ABC) inference. We introduce a method for numerically approximating ABC posteriors using the multilevel Monte Carlo (MLMC). A sequential Monte Carlo version of the approach is developed and it is shown under some assumptions that...
Bayesian statistical inference under unknown or hard to asses likelihood functions is a very challenging task. Currently, approximate Bayesian computation (ABC) techniques have emerged as a widely used set of likelihood-free methods. A vast number of ABC-based approaches have appeared in the ...
