Optimal Crossover Designs for the Comparison of Two Treatments in the Presence of Carryover Effects and Autocorrelated Errors
研究两种治疗交叉实验中,考虑直接效应、一阶残留效应和自相关误差的模型,提出最小化治疗效应估计方差的设计方法,并给出三、四期情况下的显式结果及实用设计效率。
A model for responses in a crossover experiment that includes direct and first-order carryover treatment effects, together with an autocorrelated error term, is considered when there are two treatments. A method for generating designs that minimize the variance of the estimated treatment effects is proposed and explicit results are given for the three and four period cases. Efficiencies of some practical designs are calculated.
