Summary

This chapter analyzes four example data sets from two-phase studies. The studies illustrate key aspects regarding analytic choice and interpretation. Computational aspects are described in considerable detail for each example. A study reported by Burk was designed to evaluate the effects of the introduction of fluoridation to drinking water on cancer death rates (CDR) in the United Kingdom. Dyer et al. studied the effects of an intervention (a supervision program) on a measure of functional activity in severely handicapped students. Two of the examples describe major problems in attempting to draw causal conclusions from two-phase designs that involve long data collection periods and few observations. An example of a long series clarifies the differences between the recommended regression approaches and the more popular ARIMA approach. The nature of the models required to adequately describe data collected in very different application areas is demonstrated often to be quite simple.
