Actually, let me just do the error with line. I'll do the squared error. I don't want this to take up too much space. Squared error with line. And then the next one I want to do the squared error. Actually, no, I already had the squared error. And then the next one I am going to have the squared variation for that y value, squared from the mean y. I think these columns by themselves will be enough for us to do everything.
