The View Model dialog box displays information to help you determine whether you are using the correct model.
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.
Response Optimizer uses a model that you fit and that Minitab automatically stored in your worksheet to estimate the optimal variable values. You must fit a model before you can use the Response Optimizer. If you want to optimize multiple responses, you must fit a model for each response. The optimal values are accurate only if all models represent the true relationships between the variables.
You can fit a model with different variables for each response. However, a variable in one model cannot be the response in another model. If a variable was not included in the model for a particular response, the optimization plot for that response-variable combination will be blank.
