Dear Helmut
in one of your presentatitions it is mentioned as below
"Replicate designs
Two-sequence three-period
T R T
R T R
Sample size to obtain the same power as a 2×2×2 study: 75%
Two-sequence four-period
T R T R
R T R T
Sample size to obtain the same power as a 2×2×2 study: 50%"
could you provide the rationale to consider the sample size as 75% & 50% (of 2×2×2 study) for 3 period & 4 period replicate designs respectively?
