Good morning,
I performed a multiple regression with one Y and 6 X (this is the concrete example, taken from the enhanced datasets).
I placed the Y response variable and the 6 other variables in the "Choose model effects" field with "Add".
I clicked on "Pre-built models", I chose "Degree factorial", I left the degree at 2.
I clicked "Run".
The report does not show second-order interactions, why?
The 7 variables are of a continuous numerical type.
Thank you in advance for your answers.
Jean-Luc
Did you select the 6 data columns in the list on the left before selecting the Degree factorial = 2? Do you see the interaction terms in the list on the right before you click Run?
I selected all 6 X's from the left-hand list, but I added them before choosing "factorial degree = 2", in the order you indicated, and it works!
THANKS !
