Abstract:
|
The differences in design-based versus model-based versus model-assisted sampling strategies and inferential procedures are often not well-understood when applied to environmental and ecological research. In this presentation we describe, compare, and contrast the three approaches in several ways, including identifying strategies for sampling design, choice of estimation or inference procedures, and examining the conditions under which the approaches are optimal or at least appropriate. In addition, there will be discussion of the potential for misuse of the approaches. Several examples are given to demonstrate similarities and differences among the three approaches.
