A Finite Mixture Approach for Identification of Geographic Regions with Distinctive Ecological Stressor-Response Relationships
(Virginia Tech, 2006)
We study a model-based clustering procedure that aims to identify geographic regions with distinctive relationships among ecological and environmental variables. We use a finite mixture model with a distinct linear regression ...
Statistical Monitoring of Nonlinear Product and Process Quality Profiles
(Virginia Tech, 2007)
In many quality control applications, use of a single (or several distinct) quality characteristic(s) is insufficient to characterize the quality of a produced item. In an increasing number of cases, a response curve ...
Approaches to the Label-Switching Problem of Classification, Based on Partition-Space Relabeling and Label-Invariant Visualization
(Virginia Tech, 2006-07-15)
In the context of interest, a method of cluster analysis is used to classify a set of units into a fixed number of classes. Simulation procedures with various conceptual foundations may be used to evaluate uncertainty, ...
