Compare more than two treatment under a crossover design.
H0: margin \le \delta
Ha: margin > \delta
if \delta
>0, the rejection of Null Hypothesis indicates the superiority of the test over the control;
if \delta
<0, the rejection of the null hypothesis implies the non-inferiority of the test against the control.
