Hi all,
I have the results of a two factorial DOE with 5 independent variables and 1 outcome.
The good news is I know how to run an anova and see which effects or interaction of effects will cause that particular group to be statistically significant. The bad news is that I cannot visualize it and see HOW the interaction is affect my result! For example in below, X3 and X4 have an interaction with each other. What is the best way to graphically visualize it? Each independent variable can only be -1 or 1. Normally, this should be able to be seen in the effects plot but it is greyed out here?
