Single World Intervention Graphs : A Primer

We present a simple graphical theory unifying causal directed acyclic graphs (DAGs) and potential (aka counterfactual) outcomes via a node-splitting transformation. We introduce a new graph, the Single-World Intervention Graph (SWIG). The SWIG encodes the counterfactual independences associated with a specific hypothetical intervention on the set of treatment variables. The nodes on the SWIG are the corresponding counterfactual random variables. We illustrate the theory with a number of… Expand

Compartmental Model Diagrams as Causal Representations in Relation to DAGs
TLDR
It is shown how to use compartmental model diagrams to explicitly depict interaction and feedback cycles, as well as explicitly depict feedback cycles and interactions, as part of a long-term tradition of causal thinking in epidemiology. Expand
Decision-theoretic foundations for statistical causality
Abstract We develop a mathematical and interpretative foundation for the enterprise of decision-theoretic (DT) statistical causality, which is a straightforward way of representing and addressingExpand
Causal Calculus in the Presence of Cycles, Latent Confounders and Selection Bias
We prove the main rules of causal calculus (also called do-calculus) for i/o structural causal models (ioSCMs), a generalization of a recently proposed general class of non-/linear structural causalExpand

Limitations of individual causal models, causal graphs, and ignorability assumptions, as illustrated by random confounding and design unfaithfulness
TLDR
Even with this extension, ordinary graphical models still fail to capture distinctions between hypothetical superpopulations and observed populations, although potential-outcome models can be adapted to show these distinctions and their consequences. Expand
Summary of relationships between exchangeability, biasing paths and bias
TLDR
It is shown how bias, exchangeability and biasing paths interrelate and provide justification for key results, and it is shown that absence of a biasing path implies exchangeability but that the reverse implication need not hold without an additional assumption, such as faithfulness. Expand
Generalizing causal inferences from randomized trials: counterfactual and graphical identification
When engagement with a randomized trial is driven by factors that affect the outcome or when trial engagement directly affects the outcome independent of treatment, the average treatment effect amongExpand
Understanding Marginal Structural Models for Time-Varying Exposures: Pitfalls and Tips
TLDR
This illustration provides a step-by-step illustration of generalized computation of standardization and inverse probability weighting, as well as the specification of marginal structural models, particularly for time-varying exposures, using a novel hypothetical example. Expand
Mediation analysis for different types of Causal questions: Effect of Cause and Cause of Effect
Many statistical analyses aim at a causal explanation of the data. When discussing this topic it is important to specify the exact query we want to talk about. A typical causal question can beExpand
A Graphical Description of Partial Exchangeability.
TLDR
The utility of single world intervention graphs (SWIGs) and the sufficient component cause model are illustrated and an illustrative example of when partial exchangeability might hold in the absence of complete exchangeability is provided. Expand

TLDR
It is shown that the observed distribution of a discrete model is always restricted if any two observed variables are neither adjacent in the graph, nor share a latent parent; this generalizes the well known instrumental inequality. Expand
Adjustment Criteria in Causal Diagrams: An Algorithmic Perspective
TLDR
This work proves equivalences between existing as well as new criteria for adjustment and provides a new simplified but still equivalent notion of d-separation, enabling users to assess the effects of covariate adjustment on diagrams with tens to hundreds of variables interactively in real time.

An Axiomatic Characterization of Causal Counterfactuals
This paper studies the causal interpretation of counterfactual sentences using a modifiable structural equation model. It is shown that two properties of counterfactuals, namely, composition andExpand
Effects of Treatment on the Treated: Identification and Generalization
TLDR
The conditions under which ETT can be estimated from experimental and/or observational studies are explored, and it is shown that, when the action invokes a singleton variable, the conditions for ETT identification have simple characterizations in terms of causal diagrams. Expand
Defining and Identifying the Effect of Treatment on the Treated
The effect of treatment on the treated (ETT) is a causal effect commonly used in the econometric litetature. The ETT is typically of interest when evaluating the effect of schemes that requireExpand
Probabilistic Evaluation of Counterfactual Queries
TLDR
A formalism that uses probabilistic causal networks to evaluate one's belief that the counterfactual consequent, C, would have been true if the antecedent, A, were true is presented. Expand
An Efficient Algorithm for Computing Interventional Distributions in Latent Variable Causal Models
TLDR
An algorithm which computes interventional distributions in latent variable causal models represented by acyclic directed mixed graphs (ADMGs) to compute these distributions efficiently is proposed, which takes advantage of a recursive factorization which generalizes the usual Markov factorization for DAGs and the more recent factors for ADMGs.

Axiomatizing Causal Reasoning
TLDR
It is shown that to reason about causality in the most general third class, it must extend the language used by Galles and Pearl. Expand
