With the notation in the paper then, S(1,0)=N(0)+N(1)+...+N(k-1). I'm
not sure what N(0) is, or even if I can assume it equals zero, I don't
think the sum from N(0) to N(k-1) is what is needed to be in the
denominator of the expression for r(i) on the top of page 72.
Am I missing something? Any comments would be greatly appreciated.
