The View Model dialog box displays information to help you determine whether you are using the correct model. Minitab enables this dialog box only if you select Fitted means for a 2-level factorial design.

Note

For mixture designs, you do not need to fit the model first because the cube plot displays only data means. This dialog box is not available for mixture designs.

Minitab automatically stores the most recent model for a response variable each time you run the analysis. Any model that you previously fit for that response variable is overwritten. Therefore, verify that the current model is the correct model.

Cube Plot for a 2-level factorial design uses a model that you fit and that Minitab automatically stored in your worksheet to calculate the fitted means. You must fit a model before you can create a cube plot with fitted means. Cube plots of fitted means are accurate only if the model represents the true relationships between the variables.

For more information, go to Stored model overview.

Model type: The Response drop-down list below displays only the factorial models in the worksheet that can create cube plots.
Response: Select a response variable to see what terms are in the model for this response.
Terms: Displays the terms that are in the most recent model that you fit for the response variable. Use your knowledge of the analysis to determine whether the current terms in the model correspond to the correct model. You cannot modify the term list.
Model status: Displays the status of the model for the response variable. If the model is out of date, you need to re-fit the model before you can use the model. A model is out of date when the data have changed since you fit the model.
