Factor Analysis: Developments and Applications
Dimensionality reduction techniques are critical to the analysis of many data sets that contain information on a large number of outcomes. In this session, factor analyses and related methods are proposed, described and evaluated.
Learning Objectives: At the conclusion of the session, the participant in this session will be able to: 1. Articulate how a k-fold likelihood cross-validation can be used to evaluate factor analysis models 2. Apply differential item functioning techniques on scales and instruments used in health outcomes research. 3. Describe the advantages of a path model for investigating the influence of rural residence on health status 4. Describe and distinguish between the various types of multiple indicator problems that complicate the evaluation of large-scale program initiatives.
