Razie,
I would like to have the mathematical equations that produce the aliasing pattern in an L18
array having seven factors. For instance, I would like to see how much of the x3*x4
interaction is confounded with the main effect of x5. I would like to see this for all main
effects and two way interactions and three way and higher. Further, I would like to know how
much of the linear effects are confounded with the second order effects.
Some Taguchi references show a things called a linear graph. I have that information, and do
not need it.
