This paper investigates the utility of causal invariance for improving machine learning models in domain adaptation scenarios, particularly when limited labeled target samples are available. The research focuses on linear regression to derive theoretical bounds showing that finite-sample gains depend on the margins between candidate predictors and estimation errors. The findings suggest that causal knowledge can accelerate learning if these margins are sufficiently large, but offers no advantage if they are too small. AI
