Dominican Republic holds a 80–20 advantage over Jamaica on the Relative Advantage Index, a decisive margin.
The margin is driven by military spending (78% of the combined total, $1.0bn) and economic size (GDP) (85% of the combined total, $124bn).
1 factor — nuclear warheads — could not be scored because the figure is unpublished for at least one side.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.
