Definição: "In the statistical analysis of observational data, Propensity score matching (PSM) is a statistical matching technique that attempts to estimate the effect of a treatment, policy, or other intervention by accounting for the covariates that predict receiving the treatment. DID is a type method, Difference-in-differences matching (kernel and local linear weights)."

Definição em português: "O propensity score é uma probabilidade condicional de que o participante de um estudo receba o tratamento dadas as covariáveis observadas; assim, não só aos participantes que de fato receberam o tratamento lhes é atribuído um propensity score, mas àqueles que não receberam também lhes é atribuída essa probabilidade."
