Issues with regression using months
I am not sure what is causing the parameters to group the way they are. I am trying to predict attendance eventually based on the prediction expression from the regression.
This expression uses various positive and negative coefficients based on the different parameters multiple times. I understand how to do a prediction by hand from this but this makes the prediction profile practically unusable. Am I doing anything wrong or do I just have to go forward hand calculating my prediction?
Thank you
Re: Issues with regression using monthsDid you use the Stepwise platform to select the model? It uses a unique parameterization or coding that is not used in any other platform, such as Fit Least Squares.
Please see this explanation.
