摘要 在进行随机区组试验设计时,若试验的处理数大于每一配伍组中能容纳的观察单位数时,需用平衡不完全配伍组设计。本文介绍了当资料不服从正态或各处理组方差不齐时所用的秩和检验方法,当每个配伍组中实验单位数等于处理组数时,该法与Fridman法等价。 In the randomized complete block design every treatment is applied in every block. However,it is sometimes impractical or impossible for all of the treatment to be applied to each block. In these situations, the balanced incomplete block(BIB) design is employed. This paper presented a rank sum test that may be used if the normality or homogeneity of variance assumptions are not met. The rank sum test reduces to the Fridman's test if the number of treatments equals the number of experimental units per block. The method is illustrated with an example.
