Dear all，

When using Crossover for Tmax testing, how can I judge whether it is equivalent by the result?

I read the "The nonparametric methods proposed by Koch (1972)" document, and I think he is doing the following steps to judge:

1. Determine if the P value of the sequence is greater than 0.05,
2. If the P value of the sequence is less than 0.05, the test of "Treatment" cannot be performed.
3. If the P value of the sequence is greater than 0.05, it is judged whether the P value of the treatment is greater than 0.05.
4. If the P value of the Treatment is greater than the equivalent, otherwise it is not equivalent.

5. If the P value of the sequence and the P value of the Period are both greater than 0.05, a sign test can be used instead of the rank sum test used in the above steps.

Assuming α = 0.05, all of the above P values are the results in the "Effects" table.

Is the above judgment process correct?
If not, what is the correct judgment process?
