Causation, Prediction, and Search, Peter Spirtes, Clark Glymour, Richard Scheines, 2000 (MIT Press)DOI: 10.7551/mitpress/1754.001.0001 - A fundamental text in causal inference, detailing methods for causal discovery from observational data, including the use of Partial Ancestral Graphs (PAGs) to handle latent confounders.
Causality: Models, Reasoning, and Inference, Judea Pearl, 2009 (Cambridge University Press) - The authoritative book on Structural Causal Models (SCMs) and graphical models for causal inference, providing comprehensive theory on identification, confounding, and bias, including discussions that necessitate advanced graphical representations.
Ancestral graphs, Thomas S. Richardson, Peter Spirtes, 2002The Annals of Statistics, Vol. 30 (Institute of Mathematical Statistics)DOI: 10.1214/aos/1031689015 - This paper formally introduces Maximal Ancestral Graphs (MAGs) and their properties, establishing m-separation as a criterion for conditional independence in the presence of latent variables.
Elements of Causal Inference: Foundations and Learning Algorithms, Jonas Peters, Dominik Janzing, Bernhard Schölkopf, 2017 (MIT Press) - Provides a modern, machine learning-oriented perspective on causal inference, covering foundational concepts of SCMs and the challenges that arise in complex systems, leading to the need for advanced graphical models.
