Hello Gann thank you for your question. The fitted line plot tool contained in Stat > Regression > Fitted Line Plot can be used for linear, Quadratic and Cubic models. Now the Fit Regression Model option contained in Stat > Regression > Regression > Fit Regression Model starts as a linear equation but you can request a quadratic or cubic model by clicking on Model and then in the option Terms Through Order select 3. This adjusts the command so it executes quadratic and cubic analysis on your model. You can confirm this by executing the Factorial Plots after running this command and confirming the line has changed to a curve. Please let me know if this answers your question. Thank you!

You spoke too fast
I thought it was only me here. Otherwise, valuable materials shared...
Thanks for this educative video. How about using it for multiple independent variables?
Thankyou so much
Thanks
How can we add more decimal to the equation showed at Minitab?
Is Fit Regression also a Simple Linear Regression?
