Can someone help me out or provide clues as to what I'm doing wrong?  When I run a regression on the unstable rates, my residual plots do not appear to be a V-shape like they should be.  I am using the same regression equation that the template uses (the UnstableRatesData tab), and I still cannot duplicate the residual plots graph on the template.  Could I be making a mistake with how I use the Excel regression function?  I click on "regression", input my Y range values and X range values, and it performs the regression.  I have tried reformatting the axis of the graph and that doesn't seem to help either.  Any help is extremely appreciated!
