Design of a Screening (Plackett-Burman) Experiment

Click the OK button on the Design & Analysis of Screening Experiments dialog to display the Design of a Screening (Plackett-Burman) Experiment dialog (if you have chosen to design an experiment via the Design experiment tab). This dialog contains four tabs: Quick, Display design, Add to design, and Generators & aliases. Use the options on these tabs to view the different aspects of the desired design. The Summary box (described below) is available regardless of which tab you select.

Summary box

The Summary Box at the top of the dialog displays the characteristics of the basic design, including the design resolution (see the Introductory Overview). Note that this information will not be updated if you add replicates to the design, or request center points or foldover.

Copy button Click the Copy button to copy either the selected text (if text has been selected) in the Summary box or all of the text (if no text has been selected) to the Clipboard. Note that the copied text retains formatting information (such as font, color, etc.).

Contract/Expand button Click the Contract/Expand button to contract or expand the Summary box. When contracted, you can see only one line of the Summary box text and can scroll through the text using a scroll bar. Note that when contracted the text is scrolled so that the first non-blank line is at the top. When expanded (the default setting), the entire Summary box will be displayed on the Results dialog.

Summary

Click the Summary button to display a spreadsheet specifying the settings for each experimental run. The design display is affected by the settings of the options on the Display design tab (see Denote factors, Order of runs, and Show (in Spreadsheet). To save the design, select the spreadsheet and use the Save or Save As options via the File menu. Note that if you request to display Text labels in your spreadsheet via the Display design tab, and then save it as a data file, then STATISTICA will save the text labels along with the "underlying" factor minima and maxima.
