Main Effects and Interactions for Screening (Plackett-Burman) Experiments
Both the Quick tab and the ANOVA/Effects tab of the Analysis of a Screening Experiment with Two-Level Factors dialog box contain the Summary: Effect estimates button. Click this button to produce a spreadsheet with the ANOVA effect estimates and coefficients for the coded model. The effects that will be computed depend on the current model, as specified via the options in the Include in model group box on the Model tab. If an error term for the ANOVA is available, then this spreadsheet will also include the standard errors of the parameter estimates and coefficients, their confidence intervals, and their Statistical significance.
All estimates in this spreadsheet pertain to the coded factor settings, that is, to the factor settings scaled to the ±1 range. To see the results for the original (untransformed) factor settings, click the Regression coefficients button on the ANOVA/Effects tab.
C = 1 | if the point is a center point |
0 | otherwise |
