## Decision of confidence interval of three period BE study [General Sta­tis­tics]

Hi,all

I am curious of the confidence interval decision of three treatment, three sequences, cross over BE study as below, if the goal is to prove the equivalence of any two of them (T1 and R or T2 and R). Will the CI still determined as 95% or 90%?

Sequence/Period  1  2  3        1          R  T1 T2       2          T1 T2 R        3          T2 R  T1

I also want to know how to select the suitable design between latin squares and William design when there exists three treatment, R T1 T2.
