WebJul 1, 2007 · We develop a method for assessing uncertainty about quantities of interest using urban simulation models. The method is called Bayesian melding, and extends a previous method developed for macrolevel deterministic simulation models to agent-based stochastic models. Webfactors. It can be viewed as an instance of the Bayesian meld-ing framework for inference about deterministic simulation models (Poole and Raftery, 2000), and its implementation is quite straightforward.

WebWe refine that model (Thomas and Clark, 2008) and implement the Bayesian melding with IMIS estimation method (Raftery and Bao, 2010). This method allows us to estimate the parameters of the Heuveline model with robust measures of uncertainty and to quantify uncertainty in the model outputs, e.g. forecasts. We validate the model and estimation ... WebA challenge for practitioners of Bayesian inference is specifying a model that incorporates multiple relevant, heterogeneous data sets.
