Associated with each node of a DAG
that has at least one parent is a set of conditional probabilities.
We use seemingly unrelated regressions (similar results are obtained using ordinary least squares) to fit a structural equation model on the innovations from the ECM for each of the 96 alternative DAGs
See text for details on how DAGs
indicate causal and noncausal associations between variables.
Starting from a digraph representing a social community, different steps of preprocessing compresses the original digraph to a DAG
Locally, for example within a basic block, a representative DAG
can be constructed.
In addition, the application of innovation accounting in this study is different from most other studies in the sense that we use the causal ordering of variables, as indicated by the estimated DAGs
, for the orthogonalization of the contemporaneous innovation covariance; as suggested by Swanson and Granger (1997), this step is crucial in providing sound inference in innovation accounting techniques.

We identified nine potential confounders and intermediate covariates a priori using directed acyclic graphs (DAGs
) (see Supplemental Material, Figures S2A,B,C for total, prenatal, and postnatal exposure DAGs
, respectively): maternal prepregnancy body mass index (BMI, continuous), maternal age (years, continuous), education (low, medium, high), smoking during pregnancy (yes/no), Roma ethnicity (yes/no), nulliparous (yes/no), gestational age (weeks, continuous), birth weight (kilograms, continuous), total breastfeeding (months, continuous), maternal gestational weight change (kilograms).
The computational workflow of the Modeling system is defined by means of DAGs
(Direct Acyclic Graph).
