I am trying to generate a design using Algdesign and came across terms of
"exact design" and "approxiamte theory design", I did not find a reference
to explain what they are, could some one shed some light about this on me?
Another question is, I want to measure the main effects and at least two
interactions, variables are factors, how do I ensure this in formula,
~.+v1:v2 +v3:v4 ?
