Mallows Cp equals number of parameters for all my Regression runs

Troubleshooting


Problem

I have been reviewing some output from a dataset and noticed that Mallow's Cp values being reported in the model Summary table are consistently equal to the number of variable plus one. Why is this happening? Can you tell me what the algorithm is and what all the equation variables are in full detai,l as well as where I can find this information and the values? I am aware of the equation listed in the Algorithms SPSS PDF under Regressions but I do not have the definition of the terms in the equation.
