The Bayesian and Approximate Bayesian Methods in Small Area Estimation
Title of dissertation: THE BAYESIAN AND APPROXIMATE BAYESIAN METHODS IN SMALL AREA ESTIMATION Santanu Pramanik, Doctor of Philosophy, 2008 Dissertation directed by: Professor Partha Lahiri Joint Program in Survey Methodology For small area estimation, model based methods are preferred to the traditional design based methods because of their ability to borrow strength from related sources. The i...
متن کاملApproximate methods in Bayesian point process spatial models
A range of point process models which are commonly used in spatial epidemiology applications for the increased incidence of disease are compared. The models considered vary from approximate methods to an exact method. The approximate methods include the Poisson process model and methods that are based on discretization of the study window. The exact method includes a marked point process model,...
متن کاملA comparison of emulation methods for Approximate Bayesian Computation
Approximate Bayesian Computation (ABC) is a family of statistical inference techniques, which is increasingly used in biology and other scientific fields. Its main benefit is to be applicable to models for which the computation of the model likelihood is intractable. The basic idea of ABC is to empirically approximate the model likelihood by using intensive realizations of model runs. Due to co...
متن کاملApproximate Bayesian methods for kernel-based object tracking
A framework for real-time tracking of complex non-rigid objects is presented. The object shape is approximated by an ellipse and its appearance by histogram based features derived from local image properties. An efficient search procedure is used to find the image region with a histogram most similar to the histogram of the tracked object. The procedure is a natural extension of the mean-shift ...
متن کاملAdaptive approximate Bayesian computation
Sequential techniques can enhance the efficiency of the approximate Bayesian computation algorithm, as in Sisson et al.’s (2007) partial rejection control version. While this method is based upon the theoretical works of Del Moral et al. (2006), the application to approximate Bayesian computation results in a bias in the approximation to the posterior. An alternative version based on genuine im...
