In philosophy of science, a causal model (or structural causal model) is a conceptual model that describes the causal mechanisms of a system. Causal models can improve study designs by providing clear rules for deciding which independent variables need to be included/controlled for. They can allow some questions to be answered from existing observational data without the need for an interventional study such as a randomized controlled trial. Some interventional studies are inappropriate for ethical or practical reasons, meaning that without a causal model, some hypotheses cannot be tested.

  • Un modello causale è un modello astratto che descrive il meccanismo causale di un sistema. Il modello deve esprimere più di una correlazione, poiché la . definisce un modello causale come un insieme ordinato di tre elementi , in cui U è a sua volta un insieme di variabili esogene i cui valori sono determinati da fattori esterni al modello; V è un insieme di i cui valori sono determinati da fattori interni al modello; ed E è un insieme di che esprimono il valore di ciascuna variabile endogena come una funzione dei valori assunti dalle altre variabili in U e V.
