| New Methods for Analyzing and Modeling Complex Data in Interdisciplinary Research |
| Multi-level and complex data in the field are usually analyzed by conventional statistical methods, which may violate important assumptions, ignore internal associations, and lose rich information within the data; therefore, may generate misleading results and lead to incorrect conclusions. The purpose of this symposium is to introduce four new analytic and modeling methods for multi-level and complex data: Generalized estimating equation, structural mean modeling, social network analysis, and agent-based modeling. After providing an overview of these four methods, their applications in physical activity and health behavior research will be described in detail through several examples and computer software/program demonstrations. |
