Lithuania holds a 65–35 advantage over Latvia on the Relative Advantage Index, a clear margin.
The margin is driven by military spending (63% of the combined total, $3.0bn) and economic size (GDP) (66% of the combined total, $84.9bn).
1 factor — nuclear warheads — could not be scored because the figure is unpublished for at least one side.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.
