Longitudinal Regression Methods
Pages 40

For the most part, the regression techniques we have reviewed in this book have been equally applicable to data gathered in cross-sectional surveys, laboratory or field experiments and trials, and two-wave longitudinal studies. However, when variable sequencing and changes over time are important aspects of the research, there are new kinds of questions that can be asked and an additional range of data analytic options. This chapter is intended to provide an introductory bridge to the more complex regression-based methods for answering research questions with data characterized by multiple assessments over time.
