	Hi Neethu! How many treatments? Are you talking about a simple cross-over (three treatments) or a replicate design (two treatments)? — Regards, Jaime

	Hi Neethu! ❝ [...] There will be three treatments. In such a case you assume a common variance. You can aplly the same methods you would use for a conventional 2×2 cross-over. — Regards, Jaime
