二个处理交叉试验结果分析的t检验法

The Method of t-test of Experimental Result of Cross-over Deign with Two Treatments

提出 2个处理、2个时期与 2个处理、3个时期交叉设计试验结果分析的t检验法。该法与Lucas方差分析法等价 ,但计算简便 ;并指出 ,在将试验个体分为两组时 ,两组个体数可以不相同 ;还给出了 2个处理、4个时期与 2个处理、5个时期交叉设计试验结果d值的计算式 。

The t test method of experimental result of cross over designs with two treatments and two stages and two treatments and three stages is presented. Compared with the method of lucas'Analysis of variance, the t test method is of equal value and wimpler. It is pointed out that the individual number of two groups is not the same when experiment individuals were divided into two groups. Caculation formula of d valuce of cross over designs of two treatments and four stages and two treatments and five stages are provided, and differencial significance has been tested by using the t test method presented in this paper.
