Design of a Mixture Experiment - Add to Design Tab

Select the Add to design tab of the Design of a Mixture Experiment dialog to access the options described here.

Add to the design

Use the options in the Add to the design group box to add replications or columns to the standard design.

Number of genuine replicates

Enter a number in the Number of genuine replicates box (or adjust the number using the microscrolls) to replicate the complete design the respective number of times. For example, if you enter a 1 into the box, then STATISTICA adds one replicate to the design, resulting in two identical complete designs. If you want to replicate selected points from the design (e.g., so that you can later obtain an estimate of pure error; see the Introductory Overview), first display the design (via the Summary: Display design option on the Quick tab or Display design tab), add rows to the spreadsheet (use option Insert - Add Cases), and then copy and paste the respective runs into those new rows.

Number of blank columns (dep. vars).

Enter a number in the Number of blank columns box (or adjust the number using the microscrolls) to add the respective number of blank columns to the displayed design (via the Summary: Display design option on the Quick tab or Display design tab). This option is useful if you want to print the spreadsheet with the extra columns to use as a convenient data entry form.
