Hi Helmut/SP,

» Maybe it is better to opt for a modified Williams’ design T₁T₂RR | T₂RT₁R | RT₁RT₂ | RRT₂T₁ which gives
» T₁•RR | •RT₁R | RT₁R• | RR•T₁ and
» •T₂RR | T₂R•R | R•RT₂ | RRT₂•
» At least balanced for T₁ and T₂ (once in every period).
» However, we have R twice in periods 1&2 and only once in periods 3&4.

If we consider modified Williams’ design with this sequence T1T2RR | T2RT1R | RT1RT2 | RRT2T1 Then,

What would be change in Proc GlM / Proc Mixed for Calculate Swr, 95% Upper bound (Scaled), and 90% CI (Unscaled) :confused:

:confused:

:confused:

.

Thanking you in advance!! :-)
