Use Define Custom Mixture Design to create a design from data you already have in the worksheet. For example, you may have a design that you created using Minitab session commands, entered directly into the Data window, imported from a data file, or created with earlier releases of Minitab. You can also use Define Custom Mixture Design to redefine a design that you created with Create Mixture Design and then modified directly in the worksheet.
Custom designs allow you to specify which columns contain your components and other design characteristics. After you define your design, you can use Modify Design, Display Design, and Analyze Mixture Design.
Components: Enter the columns that contain the component data. Data must be in the form of amounts. When the mixture total is one, amounts and proportions are equivalent.
Process Variables (optional): Enter any process variables you want to include in your design
Mixture Amount
Constant: Choose if you only have one mixture total.
In Column: Choose if you have more than one mixture total. That is, you have a mixture-amount experiment.
