Alternatives to Simonton's analyses of the interrupted and multiple-group time-series designs.

D. K. Simonton (see record 1978-00178-001) discussed the use of several linear models for the analysis of data arising in the interrupted time-series design and the multiple-group time-series design. The present authors contend that the objectives of Simonton's analyses can be realized using profile analysis. Statistical procedures for analyzing the interrupted time-series and the multiple-group time-series designs are outlined. The procedures are applicable when several Ss are observed on several pre- and posttreatment occasions and when the number of Ss is greater than the number of occasions.
