一种双随机化程序，规范随机化，被提议用于行为和教育干预，其中包含单例多基线设计的逻辑。新方法在概念上和方法上都比以前开发的方法更清晰，因为受调节的随机化保持了多基线设计的基本完整性（即，在实验单元之间系统地交错引入干预措施），同时在统计上可行，单位较少（N < 4）。此外，以前提出的多基线数据的非参数分析可以归入一般的调节随机化公式，调节随机化方法为研究人员提供了一个灵活的分析工具，可以考虑到具体的实质性，方法学和统计权衡。
A dual-randomization procedure, regulated randomization, is proposed for behavioral and educational interventions that incorporate the logic of single-case multiple-baseline designs. The new approach is sharper conceptually and methodologically than previously developed approaches in that regulated randomization maintains the basic integrity of the multiple-baseline design (namely, the systematically staggered introduction of the intervention across the experimental units) while being statistically practicable with fewer units (N < 4). Moreover, previously suggested nonparametric analyses of multiple-baseline data can be subsumed by a general regulated randomization formula, The regulated randomization approach provides researchers with a flexible analytic tool that can take into account specific substantive, methodological, and statistical trade-offs.
