Objective:
The objective of this research project is to develop approaches for spatio-temporal design and modeling to further the understanding of aquatic resources. This is one of several projects conducted by the STARMAP Center. The progress of the other projects is reported in separate reports (see the Annual Reports for R829095 and R829095C002 through R829095C005).
Progress Summary:
With the addition of five new research areas and impressive output from the existing subprojects, the Combining Environmental Data Sets (R829095C001) group was quite productive in Year 3 of the project. Numerous A large papers were submitted to peer-reviewed journals and a number of talks were given, including several invited talks and one keynote address (Dr. Davis). These talks were presented to a number of audiences, including user communities. Highlights of the year include: completion of the Statistical Computing book and delivery of short courses (Dr. Hoeting); an important new interaction with the City of San Diego and submission of a related paper (Drs. Ritter, Leecaster, and Urquhart); submission of three papers by Gitelman (and co-authors) on three different subjects; submission and acceptance of a paper by Drs. Hoeting, Merton, and Davis; submission of a paper by Drs. Johnson and Hoeting; and establishment of a new subcontract with the University of Alaska–Fairbanks (UAF) to support Dr. Johnson’s continued work. Graduate students Kathi Georgitis (Oregon State University [OSU]), Megan Dailey (Colorado State University [CSU]), and Joshua French (CSU) have joined the Space-Time Aquatic Resources Modeling and Analysis Program (STARMAP) project. Andrew Merton’s Ph.D. research continues. Mr. Merton won an award for best student paper at an American Statistical Association (ASA) conference.
Specific Areas of Research
Book on Statistical Computing. Participants: J. Hoeting and G. Givens (CSU)
- Goals: To complete a book on statistical computing.
- Year 3 Outcomes: The book is essentially complete, with minor copy editing still remaining. A Web page has been created. Drs. Hoeting and Givens presented two short courses in Chicago, in October 2004, at a conference on Computational Environmetrics, which was co-sponsored by the Section on Statistics and the Environment (ASA) and the Center for Integrating Statistical and Environmental Science (CISES) at the University of Chicago.
- Upcoming: Possible short course to be given at the Joint Statistical Meetings (JSM) in Minneapolis, Minnesota, in August 2005. The book is expected to appear in early 2005.
Models for Compositional Data. Participants: D.S. Johnson and J.A. Hoeting
- Goals: To develop new models and methodology for the analysis of compositional data. These models will be used to develop a better understanding of species traits of benthic invertebrates and may be useful in the development of indicators of stream fitness.
- 2004 Outcomes: Devin Johnson assumed a position in the Department of Mathematical Sciences at UAF in August 2003. He continues to work with STARMAP through a subcontract from CSU to UAF that started in summer 2004. He is participating in the development of a program in environmental statistics. Drs. Hoeting and Johnson submitted a manuscript to The Annals of Statistics in January 2004. An additional manuscript is being prepared for possible submission to The Journal of the American Statistical Association in 2005. Dr. Johnson gave invited talks at JSM in Toronto in August 2004, and at the Conference on Computational Environmetrics in October 2004 at the University of Chicago. He also gave a presentation at the STARMAP conference in Fort Collins, CO.

Design and Analysis Methods for Geo-Referenced Binary Data. Participants: M. Leecaster (Idaho National Engineering and Environmental Laboratory), K.J. Ritter (Southern California Coastal Water Research Project [SCCWRP]), and S.B. Weisberg (SCCWRP)
- Goals: To determine appropriate grid size for producing maps using Markov random field models and compare to geostatistical modeling approaches.
- Year 3 Outcomes: This work has progressed from theory to application with a design implemented and executed by the City of San Diego in summer 2004. Ritter gave presentations at the Southern California Academy of Sciences Meeting, the Graybill Conference and the 2004 STARMAP/Designs and Models for Aquatic Resource Surveys meeting. A manuscript has been submitted to Ecological and Environmental Statistics.
- Upcoming: The contract has been completed; there is the possibility for funding in 2005.
Geostatistical Models: Model Selection and Asymptotics. Participants: A. Merton (CSU doctoral student), J. Hoeting, and R. Davis
- Goals: To produce new methodology and perhaps new theoretical results related to model selection for geostatistical models.
- Year 3 Outcomes: A paper was accepted and will appear in Ecological Applications in 2005. Dr. Hoeting presented at the National Science Foundation (NSF) Conference on Statistics and Ecology in Jackson Hole, Wyoming, in December 2003. Dr. Davis gave the keynote address at the International Biometrics Conference in Cairns, Australia, in July 2004. Mr. Merton presented at the ASA Colorado-Wyoming Chapter Spring Meeting in Boulder, Colorado, in April 2004 (best student presentation award); the JSM in Toronto in August 2004; and the Monitoring Science and Technology Symposium in Denver, Colorado, in September 2004.
- Upcoming: Mr. Merton has been invited to present at the 33rd Annual Meeting of the Statistical Society of Canada and at the Western North America Region of The International Biometric Society (WNAR) Annual Meeting, both in June 2005. Mr. Merton will have his Ph.D. preliminary exam on this work in late 2004. His goals continue to be to earn his doctoral degree and publish additional papers.
