Statistical Models and Techniques for the Analysis of Conditions of an Ecological System

This chapter treats the contribution of statistical research and applied statistics to ELAWAT. In the introduction the role of applied statistics in scientific research is described. Definitions of statistical terms and expressions are given to make the subsequent statements definite. The main part of the chapter introduces statistical models and methods. They are arranged according to the ecologically relevant terms in ELAWAT: pattern, process, relation, and distinction between states of a system. Each paragraph starts with an ecological question and treats statistical models and methods useful for finding an answer. Case studies with data from ELAWAT demonstrate some of the methods for data analysis and interpretation. The final paragraph summarizes the methods applied in ELAWAT.
