1 Modeling in the presence of uncertainty: Is there another way to do it? Jennifer Hoeting Colorado State University

2 New conference title: “The movers and shakers of ecological modeling” A big thank you to the workshop organizers: Noel, Jim, Jay, Kate, Chris; and the faculty and staff of MBI … even if this conference did force a University of Michigan alumna to attend a function at archrival Ohio State – Go Blue!

3 Two Themes for Discussion 1.Uncertainty 2.Graduate Education

4 Uncertainty Are we doing enough (yet) to convey uncertainty in analyses of ecological problems? Does too much focus on uncertainty distract from the main point of our analyses (inference)?

5 Uncertainty: Is there a best method for model selection/specification? Bayesian (e.g., Gelfand): use MANY parameters and let the data speak for themselves Semi-parametric (e.g., Breidt): combine model-based and design-based inference Likelihood (e.g., Burnham): AIC is taking the world of ecology by storm. Is this “new religion” the right direction for ecology?

6 Uncertainty: Is there a best method for model selection/specification? Does our choice of model or analysis depend on whether the data are from a probability-based sample (Breidt) or an observational study (Gelfand and Breidt)? Are covariates really “known covariates”?

7 Graduate Education Are we equipping our graduate students with the right tools to become the next Cressie, Gelfand, Clark, Hastings, or insert your name here? How much ecology do I need to know?

8 Graduate Education If the focus is to train statisticians who will impact ecology, what is the right blend of traditional and modern statistical methods in graduate study? Multi-disciplinary is all the rage in academia. Does an interdisciplinary degree water down a statistics or ecology degree?
