... tail confidence interval with nominal coverage set at 0.95. The last three box-plots show the sampling distribution of some specific quantiles (namely the 2.5th, the median and the 97.5th percentiles) of the approximated ... See full document

... The accuracy of estimation is expected to depend on the acceptance rate e in a way determined by a trade-off be- tween bias and variance (e.g., Beaumont et al. 2002). While the RAE measures only the error of the ... See full document

... Modern statistical applications increasingly require the fitting of complex statistical models. Often these models are intractable in the sense that it is impossible to evaluate the likelihood function. This excludes ... See full document

... Approximate Bayesian Computation (ABC) techniques are a suite of model fi tting methods which can be im- plemented without a using likelihood ...reducing computation time and improving accuracy ... See full document

... We propose a more flexible approach than existing methods to estimate the mean and standard deviation for meta-analysis when only descriptive statistics are available. Our ABC method shows comparable per- formance to ... See full document

... The most popular approach to deal with the curse of dimensionality in ABC is dimension reduction. Here, high- dimensional datasets are mapped to lower dimensional vectors of features, often referred to as summary ... See full document

... In order to demonstrate that ABC can be tractably applied to pa- rameter estimation in contemporary LSS analyses, we narrow our focus to inferring the parameters of a halo occupation distribution (HOD) model. The ... See full document

... Composite likelihood methods that evaluate the entire allele frequency spectrum (AFS) across many populations may also prove useful for inference in situations such as the one presented here (Gutenkunst et al. 2009). ... See full document

... In this paper we derive a system identification framework for continuous-time nonlinear systems, for the first time using a simulation-focused computational Bayesian approach. Simulation approaches to non- linear ... See full document

... During the last decade, the ABC algorithm has been applied in many areas for both levels of inference (parameter and model): genetics [19], biology [20,21] and psychology [22]. The rapid developments and continuous ... See full document

... Corollary 4.2 shows that this result holds whether we fix the number of accepted samples (controlling the precision of our estimates but allowing the computational cost to be random) or fix the number of proposals ... See full document

... In this study we used a stochastic compartmental model, whose structure is similar to one previously devel- oped for BTV (Gubbins et al., 2008; Szmaragd et al., 2009), and fit this to data on the seroprevalence of SBV in ... See full document

... This process works for different measures of interest (e.g. pedestrian flow, fundamental diagram, trajectories), as long as a suitable distance function linking data to simulation can be found (step 4 above). Provided ... See full document
