Hello everyone,
I am trying to model a linear model with the least squares method.
In my model I can choose if I want to add a constant or not.
When I add a constant I obtain a value for my R square, however when I build a model without the constant my R square is not displayed.
Example with the “ BigClass ” table:
How can we solve this problem and obtain the R squared if we want a model without a constant?
Thank you for your reply.
