JSM 2005 Online Program

Abstract #304015

This is the preliminary program for the 2005 Joint Statistical Meetings in Minneapolis, Minnesota. Currently included in this program is the "technical" program, schedule of invited, topic contributed, regular contributed and poster sessions; Continuing Education courses (August 7-10, 2005); and Committee and Business Meetings. This on-line program will be updated frequently to reflect the most current revisions.

Abstract:	Resolving statistical issues for ecological monitoring programs often has been hindered by failure to dedicate adequate resources to design and analysis. This thesis is explored using, as a case study, the Upper Mississippi River's Long Term Resource Monitoring Program (LTRMP). The LTRMP's $5 million per annum program was initiated in 1988 and switched to the use of probabilistic designs in 1993; it samples approximately 100 water, fish, vegetation, and invertebrate variables. The designs are stratified random with nonproportional sampling among spatial strata; some variables are sampled annually and others multiple seasons per year. Objectives include both estimating status and trends and ecological research using primarily monitoring data. Despite the relative complexity of the program, resources devoted to statistical support have historically been meager: 0% of budget in 9 of 18 years and 1% of budget in the remainder. The sources of this mismatch are explored, as are the program's analytical accomplishments, current challenges, and lessons learned.
