Hi BE-proff,

❝ There is 2x2x2 crossover design by default but I'd like to have 2x2 crossover


Some thing. The order (mostly!) is treatment × sequence × period. You find 2×2×2 and 2,2,2 in the literature. If not “higher-order” or “Williams” is given, two treatments are assumed. Therefore, you find also 2×2 or 2,2. Statisticans are used to AB/BA, AB|BA, RT|TR, etc. If they say “A-Bee-Bee-A” they mean 2×2. Don’t wait for the second sequence of a fully replicated design. It’s a mess. BTW, in PowerTOST type known.designs().

❝ 2. I tried to enter concentration data manually without csv file (just for training) and after it bear returned Enter the file name (no extension!): :confused:


Never done that. Maybe a permission issue. Try this (untested):
