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.
Comparisons uses a model that you fit and that Minitab automatically stored in your worksheet to estimate the differences between group means. You must fit a model before you can compare means. Comparisons are accurate only if the model represents the true relationships between the variables.
