To use Analyze Mixture Design, you must first create and store the design using Create Mixture Design, or create a design from data that you already have in the worksheet with Define Custom Mixture Design.
You can choose from six standard models (linear, quadratic, special cubic, full cubic, special quartic, or full quartic) or choose specific terms from a list of all estimable terms. See Selecting model terms for details.
You can also select from four model fitting methods:
Responses: Select the column containing the response variable. You may enter up to 25 response columns.
Type of Model
Mixture components only: Choose to fit a model for the components only.
Mixture components and process variables: Choose to fit a model for the components and process variables.
Mixture amount experiment: Choose to fit a model for the components and the amount variable.
Analyze Components in
Proportions: Choose to fit the model in proportions.
Pseudocomponents: Choose to fit the model in pseudocomponents.
Model Fitting Method: Choose the mixture regression, stepwise, forward selection, or backward elimination.
