An interaction has occurred when two inputs have a greater impact on a change in the output than either of the inputs has by itself. This is defined as an interaction effect in statistical and experimental design contexts, where the combined effect of several factors is more significant than the individual effects of each factor.
The purpose of Design of Experiments (DOE) is to run a series of controlled experiments to understand the effect certain factors (Xs) have on a response variable (Y). One effect is called the main effect and evaluates the impact of a single factor. There are also interaction effects, which evaluate the impact of a specific combination of factors.
