Abstract

Suggests that J. Algina and H. Swaminathan (see record 1979-32689-001) have proposed more sophisticated analyses for the cross-sectional time-series experiment than did the present author (see record 1978-00178-001). Their suggested procedure for testing the empirical adequacy of the hypothesized intervention model is seen as especially valuable. Nonetheless, the greater complexity of their approach may not always be justified in many research applications. In particular, their exact-test method will normally yield statistical inferences similar to those of the present author's approximate-test procedure.
