摘要：

Forty years ago, Eugene Edgington developed a single-case AB intervention design-andanalysis procedure based on a random determination of the point at which the B phase would start. In the present simulation studies encompassing a variety of AB-type contexts, it is demonstrated that by also randomizing the order in which the A and B phases are administered, a researcher can markedly increase the procedure's statistical power.
