National Data: What Do We Learn?
摘要
The goal of this chapter is to consider some of the costs and benefitsassociated with using national data instead of state agency data (as was discussed in Chap. 3). We provide information ona list of national datasets available for research and discuss the costs and benefits of using national datasets. We discuss the implied differences in modeling between using national datasets and state agency datasets. The discussion implies that using agency data is the preferred approach.
