Figure 4.

Influence of the effect size (i.e., difference between response observations obtained during a fist intervention period and subsequent intervention periods) on the power to detect a carryover effect assuming four intervention periods (i.e., 8 intervention administration periods overall) with no washout periods based on the proposed analytical model. 50 data collections were made during each intervention administration. Each line corresponds to a different assumed serial correlation strength. The upper most line representing a 0.0 correlation, with successive lines below it reflecting serial correlations of 0.1, 0.25, 0.5, 0.75, and 0.9, respectively. A type I error rate of 0.05 was assumed.
