This is a request from a customer. They want to change a model type (Main Effect, Crossed, Nested, and so on) in a Variability / Attribute Gage Chart report. If they change the model type, they need to relaunch the dialog.
For example, some software (like Minitab) omits the interaction term from the full model if the p-value for the interaction is ≥ 0.05. This is the scenario they want to change the model type after the first analysis.
