Thank you, arl_stat,

❝ It is 2 treatment, 2 period, 2 sequence crossover study (N=50). And batches considered are as follows: Subject no. 1 to 25 as Batch-I AND Subject no. 26 to 50 as Batch-II.


In that case you have batch as a fixed between-factor where the levels correspond to groups separated in time, and I would avoid Treatment*Batch (~"treament in batch") unless you have some sneaky plan with that interaction.

Pass or fail!
