Dear ElMaestro!

❝ N=c(16, 20, 24, 28, 32, 36, 40, 44, 48, 50, 60, 70, 80, 90, 100, 110)

❝ Pwr1=c(0.712, 0.751, 0.754, 0.738, 0.718, 0.696, 0.677, 0.654, 0.637,

❝ 0.629, 0.581, 0.535, 0.493, 0.451, 0.415, 0.38)

❝ Pwr0=c(0.772, 0.856, 0.911, 0.946, 0.967, 0.98, 0.989, 0.993, 0.996,

❝ 0.997, 0.999, 1, 1, 1, 1, 1)

❝

❝ Example how to read: If we have 16 sbj in each sequence then the power

❝ with the standard requirements is approximately 77.2%

❝ (Fartssie gives 77.6%

❝ on my machine); with the Danish requirements it is approximately 71.2%.

I get 77.62276% (N=n₁+n₂=32) in . FARTSIE on my machine: 77.6228% and StudySize 77.607% (120000 Monte Carlo Simulations: 77.81% after 9 seconds on a double Xeon 2.8GHz machine).
How did you set limits for the Danish requirements?
