Tóm tắt	Dyadic conflict analysis is the dominant research design in quantitative conflict studies: it treats the pair of states (the dyad), observed year by year, as the unit of analysis and models the probability that a pair experiences militarized conflict as a function of their joint and individual attributes. Stuart Bremer's 'Dangerous Dyads' (1992) is the canonical statement, identifying which conditions — contiguity, the absence of alliance, power parity, the absence of joint democracy, and others — make a pair of states war-prone. The design aligns conflict data with the relational theories that dominate the field.	Democratic peace analysis is the empirical study of the proposition that democracies rarely or never fight one another. Building on the dyadic research design crystallized by Maoz and Russett (1993), it codes the regime type of each state, constructs dyad-years, and models the probability of militarized conflict as a function of joint democracy alongside controls for power, contiguity, alliances, and trade. The approach has produced one of the most robust empirical regularities in international relations and a long debate over whether shared norms or institutional structures account for it.
