For a two-way ANOVA with S1U1B1(S1U1B0S1U1B1) design, the degrees of freedom for the main effect of S1U1B1 is dfS1U1B11S1U1B0 - 1 and for the main effect of S1U1B0 is dfS1U1B12S1U1B0 - 1. Therefore, for the interaction between S1U1B0 and S1U1B1, the degrees of freedom will be (dfS1U1B11S1U1B0 - 1) x (dfS1U1B12S1U1B0 - 1), which is equal to (nS1U1B11S1U1B0 - 1) x (nS1U1B12S1U1B0 - 1).
