Tóm tắt	Correlates of War (COW) analysis is the systematic, data-driven study of interstate and intrastate war pioneered by J. David Singer and Melvin Small. The COW project assembled standardized, transparently coded datasets on the membership of the state system, the wars it has fought, and the material capabilities, alliances, and disputes of its members since 1816. Singer, Bremer, and Stuckey's (1972) study of capability distribution and major-power war exemplifies the approach: combine these building blocks into state-year and dyad-year datasets and analyze, statistically, what conditions correlate with the onset of war.	Power transition analysis examines when and why war breaks out between a dominant state and a rising challenger as their relative power converges. Originating in A. F. K. Organski and Jacek Kugler's The War Ledger (1980), it holds that the international system is hierarchical and most dangerous not at moments of clear preponderance but when a dissatisfied rising power approaches parity with the dominant state — and it operationalizes this by tracking relative national capabilities over time and relating overtaking to the onset of major war.
