Implied distributions in multiple change point problems
نویسندگان
چکیده
A method for efficiently calculating exact marginal, conditional and joint distributions for change points defined by general finite state Hidden Markov Models is proposed. The distributions are not subject to any approximation or sampling error once parameters of the model have been estimated. It is shown that, in contrast to sampling methods, very little computation is needed. The method provides probabilities associated with change points within an interval, as well as at specific points. Date: June 20, 2011.

A Comparison of Methods for Anticipating and Understanding Uncertainty of Outputs from Transportation and Land Use Models
Uncertainty is important to appreciate in the outputs of complex and dynamic urban systems. This study demonstrates three methods for uncertainty propagation in transportation and land use models: Local Sensitivity Analysis with Interaction (LSAI), Monte Carlo (MC) methods, and Bayesian Melding (BM) method. Two case study settings are used to illustrate how these methods work, allowing for inte...
متن کاملBayesian change point estimation in Poisson-based control charts
Precise identification of the time when a process has changed enables process engineers to search for a potential special cause more effectively. In this paper, we develop change point estimation methods for a Poisson process in a Bayesian framework. We apply Bayesian hierarchical models to formulate the change point where there exists a step < /div> change, a linear trend and a known multip...

The problems of sequential change-point have several important applications in quality control, signal processing, and failure detection in industry and finance and signal detection. We discuss a Bayesian approach in the context of statistical process control: at an unknown time τ, the process behavior changes and the distribution of the data changes from p0 to p1. Two cases are consi...
متن کاملImproving the Performance of Bayesian Estimation Methods in Estimations of Shift Point and Comparison with MLE Approach
A Bayesian analysis is used to detect a change-point in a sequence of independent random variables from exponential distributions. In This paper, we try to estimate change point which occurs in any sequence of independent exponential observations. The Bayes estimators are derived for change point, the rate of exponential distribution before shift and the rate of exponential distribution after s...
متن کاملFitting multiple change-point models to data
Change-point problems arise when di/erent subsequences of a data series follow di/erent statistical distributions – commonly of the same functional form but having di/erent parameters. This paper develops an exact approach for 3nding maximum likelihood estimates of the change points and within-segment parameters when the functional form is within the general exponential family. The algorithm, a...
