It's pretty clear what happens here with the interaction.
Back to the main designs in the book.
All other results are now in results 2, since they take a lot of time to compile but are not subject of investigation in the moment.
TODO: If we create a fast method without saving the intermediate designs, we want to undo this.
Remark about link matrix.
Reproducing the table from the book.
Values are fine.
Yes, I agree with this (and also checked that for all other designs in all other models the pairwise differences of the first and second pair of parameters (where they exist) are estimable). Nevertheless the treatment differences are estimable in the models 2, 6 and 7 for design 11.
Added model no. 9, warning for interaction and new function `nrOfParameters`.
Added model no. 9 and conversion of model strings to numbers.
