Nigeria holds a 84–16 advantage over Chad on the Relative Advantage Index, a decisive margin.
The margin is driven by military spending (76% of the combined total, $2.1bn) and economic size (GDP) (93% of the combined total, $252bn).
1 factor — nuclear warheads — could not be scored because the figure is unpublished for at least one side. Those factors are excluded and the remaining weights renormalised, never substituted.
