Description:

Causal inference from non-interventional data -- foundations and recent approaches

Inferring the causal structure between n random variables X_1,...,X_n from passive observations (that is, when no interventions are possible) is a challenging task. Since the 1990s there is an increasing community of researchers that believe that causal inference is possible under appropriate assumptions. They have developed methods that rely on conditional statistical (in)dependences, based on the Causal Markov Condition and Causal Faithfulness [1,2]. More recently, it has been shown that not only statistical independences but also other properties of distributions reveal causal information [3]. We have applied some of the methods successfully in brain research [4]; evaluations of the methods on real data with known causal structure also show encouraging results [5].

The methods can be justified by a principle that states the following asymmetry between cause and effect: P(cause) and P(effect|cause) contain no information about each other, while P(effect) may contain information about P(cause|effect) and vice versa -- in a sense that can be formalized in various ways [3,6]. Motivated by this principle, there are also new approaches to the difficult problem of detecting hidden common causes in multivariate regression models [7].
