Thanks a lot, I understand what you meant now.
I was like you said the general the fact that the computed means used to produce de SSErr value was obviously weighted and there to get a true R2 the same weighted means had to be used in the computation for the SSTot... Thanks a lot for your patience. I wish you all to live long and prosper.
