## SAS code for the mixed effects model with sequence mistakenly assigned [Study As­sess­ment]

Dear All,

We know that the model statement in SAS for the mixed effects model to evaluate bioequivalence is
model logpkp =trtseqan aperiod trtan / ..., in which the planned sequence is used.

In a 2*2 BE study, if subject A with planned sequence T-R is assigned to R-T and B with planned R-T has the actual sequence of T-R， what code can we use for the model statement with these two subjects included for a sensitivity analysis?
