摘要：We assume that we have observational data generated from an unknown underlying directed acyclic graph (DAG) model. A DAG is typically not identifiable from observational data, but it is possible to consistently estimate the equivalence class of a DAG. Moreover, for any given DAG, causal effects can be estimated using intervention calculus. In this paper, we combine these two parts. For each DAG in the estimated equivalence class, we use intervention calculus to estimate the causal effects of t...

摘要：It is known that all resolution IV regular 2(n-m) designs of run size N = 2(n-m) where 5N/16 < n < N/2 must be projections of the maximal even design with N/2 factors and, therefore, are even designs. This paper derives a general and explicit relationship between the wordlength pattern of any even 2(n-m) design and that of its complement in the maximal even design. Using these identities, we identify some (weak) minimum aberration 2(n-m) designs of resolution IV and the structures of their com...
