    Hello,
    The equation for the adjusted R squared (I believe) is:
    Adj R sq  = 1-((1-rsq)*(n-1)/(n-p))
    where n = no. of points, p = no. of parameters including B0
    Now if there is no B0 term, is this still the equation?  Which means if you are fitting x = y then the adj r squared is the same as r squared since p = 1.
     
    Is this correct?  Thanks.
