Figure 7.2 Stage 1 Report for Main Effects
A two-degree-of-freedom error sum of squares is computed from the four runs corresponding to the two fake factors. Because the fake factors are, by construction, inactive, this estimate of error variance is unbiased. For each main effect, the main effects response YME is tested against this estimate. In this example, three factors, Methanol, Ethanol, and Time, have p-values smaller than the threshold value and are retained as active. For details about the threshold values, see Stage 1 Methodology.
The variability from the three inactive factors, Propanol, Butanol, and pH, is pooled with the fake factor sum of squares to produce the five-degree-of-freedom RMSE statistic shown in Figure 7.2.
