Model Averaging in Ecology
-
Much of statistical practice is concerned with parameter uncertainty, and ignores model uncertainty, which arises when we fit several models and find that no single model stands out as best. This course will provide you with the tools to be able to allow for both types of uncertainty. Model averaging involves estimating the parameters in a way that allows for model uncertainty, and it often provides better estimates and confidence/credible intervals than those from a single best model. The course is divided into two modules (Bayesian and Frequentist model averaging) composed of pre-recorded lecture material and hands-on exercises using R. The course is based on David Fletcher's recent book (Springer 2018), which can be found here.
-
