Design of a Screening (Plackett-Burman) Experiment - Generators and Aliases Tab

Select the Generators & aliases tab of the Design of a Screening (Plackett-Burman) Experiment dialog to access information about correlations between main effect vectors and 2-way interaction vectors.

Correlations of main effects with 2-way interactions (without foldover): Click the Correlations of main effects with 2-way interactions (without foldover) button to display a spreadsheet with the correlations between the coded main effect vectors and 2-way interaction vectors. Note that the correlations are computed for the standard design, with foldover, if the Foldover option was selected. All correlations that are greater than 0.0 will be highlighted in this spreadsheet. Thus, you can quickly identify the confounded main effects and interactions.
