Hello
I have the following model
y ~ a + b + c + d + e + f
I would like to look at all possible 3 way interaction, is it possible to do
this without typing out each interaction manually? Is there some way to run a
saturated model permitting only 2 and 3 way interactions (As opposed to
considering up to 6 way, which I do not need). any suggesting would be
greatly appreciated, thanks
Tristan
