Theoretically, we can remove these two significant factors and replace them by the interaction C x D if the interaction between C and D is significant and enough degrees of freedom. However, the degrees of freedom is not enough for us to conduct CD interaction.0.81.01.21.41.6-0.15-0.050.050.15Residual Ploty^Residual2....
