Abstract The causal compatibility question asks whether a given causal structure graph — possibly involving latent … categorical variables. Algorithms predicated on merely necessary constraints for causal compatibility typically suffer from false …-0020 , one of us introduced the inflation technique for formulating useful relaxations of the causal compatibility problem in …

assessing causal compatibility is in the presence of partial information; i.e. when some of the variables are hidden …/latent. This paper introduces the possible worlds framework as a method for deciding causal compatibility in this difficult setting … prove that the possible worlds framework can be adapted to provide a complete solution to the possibilistic causal …
