These abc algorithms generate random samples from the posterior distributions of one or more parameters of interest, θ_1, θ_2, …, θ_n.to apply any of these algorithms, (i) data sets have to be simulated based on random draws from the prior distributions of the θ_i's, (ii) from these data sets, a set of summary statistics have to be calculated, s(y), (iii) the same summary. Approximate bayesian computation (abc) constitutes a class of computational methods rooted in bayesian statistics that can be used to estimate the posterior distributions of model parameters. Approximate bayesian computing and similar techniques, which are based on calculating approximate likelihood values based on samples from a stochastic simulation model, have attracted a lot of attention in the last years, owing to their promise to provide a general statistical technique for stochastic processes of any complexity, without the limitations that apply to traditional statistical models due to the problem of maintaining tractable likelihood functions. Approximate bayesian computation via random forests. It has been successfully applied in a wide range ofscientific fields which encounter complex data and models, such as population genetics (fagundes Advantages of simulation analysis of bayesian methods is the freedom it gives the researcher to formulate appropriate models rather than be overly interested in analytically neat but scientifically inappropriate models. approximate bayesian computation and synthetic likelihoods are two approximate methods for inference, with abc vastly more Motivated by the growth in computational power and data complexity, modern approaches to this question make intensive use of simulation methods.
