Abstract The problem of causal inference is to determine if a given probability distribution on observed variables is compatible with some causal structure. The difficult case is when the causal structure includes latent variables. We here introduce the inflation technique for tackling this problem. An inflation of a causal structure is a new causal structure that can contain multiple copies of each of the original variables, but where the ancestry of each copy mirrors that of the original. To… 
The Inflation Technique Completely Solves the Causal Compatibility Problem
TLDR
It is proved that inflation is asymptotically tight, i.e., that the hierarchy converges to a zero-error test for causal compatibility, and develops a formal hierarchy of such causal compatibility relaxations.
A Combinatorial Approach to Causal Inference
TLDR
This work defines a graphical object called an possible worlds diagram, which compactly depicts the set of all possible observations, and demonstrates explicitly, using several examples, how to prove causal incompatibility.
The inflation technique solves completely the classical inference problem
TLDR
This work proves that the inflation hierarchy is complete, i.e., any distribution of the observed variables which does not admit a realization within the considered causal structure will fail one of the inflation tests.
A Combinatorial Solution to Causal Compatibility
TLDR
This paper defines a graphical object called a possible worlds diagram, which compactly depicts the set of all possible observations, and demonstrates explicitly, using several examples, how to prove causal incompatibility.
A convergent inflation hierarchy for quantum causal structures
TLDR
A first version of the quantum inflation hierarchy that is provably convergent is constructed, using a Quantum de Finetti Theorem that holds for general tensor products of C∗-algebras, generalizing previous work that was restricted to minimal Tensor products.
Semidefinite Tests for Latent Causal Structures
TLDR
This work considers the class of causal structures where all correlations between observed quantities are solely due to the influence from latent variables, and shows that each model of this type imposes a certain signature on the observable covariance matrix in terms of a particular decomposition into positive semidefinite components.
Combining Interventional and Observational Data Using Causal Reductions
TLDR
A causal reduction method is proposed that replaces an arbitrary number of possibly highdimensional latent confounders with a single latent confoundinger that takes values in the same space as the treatment variable, without changing the observational and interventional distributions the causal model entails.
Experimentally adjudicating between different causal accounts of Bell-inequality violations via statistical model selection
TLDR
The technique shows that it is possible to witness quantumness even in a Bell experiment that does not close the locality loophole, and overturns the notion thatit is impossible to experimentally test the plausibility of superdeterminist models of Bell inequality violations.
Causal compatibility inequalities admitting quantum violations in the triangle structure
It has long been recognized that certain quantum correlations are incompatible with particular assumption about classical causal structure. Given a causal structure of unknown classicality, the
J ul 2 01 9 Analysing causal structures using Tsallis entropies
TLDR
It is found that the number of independent constraints needed to characterise the causal structure is prohibitively high that the computations required for the standard entropy vector method cannot be employed even for small causal structures, so new Tsallis entropic constraints are found by generalising known Shannon constraints.

Causal Inference via Algebraic Geometry: Feasibility Tests for Functional Causal Structures with Two Binary Observed Variables
TLDR
This work provides an inductive scheme for classifying functional causal structures into distinct observational equivalence classes and demonstrates how this sort of approach provides a means of determining which causal parameters are identifiable and how to solve for these.
Causal inference via algebraic geometry: necessary and sufficient conditions for the feasibility of discrete causal models
We provide a scheme for inferring causal relations from uncontrolled statistical data which makes use of all of the information in the joint probability distribution over the observed variables
Semidefinite Tests for Latent Causal Structures
TLDR
This work considers the class of causal structures where all correlations between observed quantities are solely due to the influence from latent variables, and shows that each model of this type imposes a certain signature on the observable covariance matrix in terms of a particular decomposition into positive semidefinite components.
Inferring latent structures via information inequalities
TLDR
An information-theoretic approach is proposed, based on the insight that conditions on entropies of Bayesian networks take the form of simple linear inequalities, and an algorithm for deriving entropic tests for latent structures is described.
Information-theoretic inference of common ancestors
TLDR
This work proves an information-theoretic inequality that allows for the inference of common ancestors of observed parts in any DAG representing some unknown larger system and shows that a large amount of dependence in terms of mutual information among the observations implies the existence of a common ancestor that distributes this information.
Which causal scenarios are interesting
TLDR
It is shown that existing graphical techniques due to Evans can be used to confirm that many graphs are interesting without having to explicitly search for inequality violations, and that there exist non-Shannon type entropic inequalities that imply these graphs areinteresting.

Causal structures from entropic information: geometry and novel scenarios
TLDR
This paper treats Bell scenarios involving multiple parties and multiple observables per party, and exhibits inequalities for scenarios with extra conditional independence assumptions, as well as a limited amount of shared randomness between the parties.
On the Testability of Causal Models With Latent and Instrumental Variables
TLDR
With the help of this formula, it is possible to test whether a model involving instrumental variables may account for the data, or, conversely, whether a given variable can be deemed instrumental.
