The Estimation and Hypothesis Testing of Treatment Effects in Nonequivalent Control Group Designs when Continuous Growth Models are Assumed.
Blumberg, Carol Joyce; Porter, Andrew C.
This paper is concerned with estimation and hypothesis testing of treatment effects in nonequivalent control group designs with the assumption that in the absence of treatment effects, natural growth conforms to a particular class of continuous growth models. Point estimation, interval estimation, and hypothesis testing procedures were developed for both treatment effects and differences in treatment effects. It was found that traditional methods of data analysis are incorrect under much of this class of growth models. (Author/PN)
