Variable elimination, graph reduction and efficient g-formula

  title={Variable elimination, graph reduction and efficient g-formula},
  author={F. Richard Guo and Emilija Perkovi'c and Andrea Rotnitzky},
We study efficient estimation of an interventional mean associated with a point exposure treatment under a causal graphical model represented by a directed acyclic graph without hidden variables. Under such a model, it may happen that a subset of the variables are uninformative in that failure to measure them neither precludes identification of the interventional mean nor changes the semiparametric variance bound for regular estimators of it. We develop a set of graphical criteria that are sound…

Semiparametric Inference For Causal Effects In Graphical Models With Hidden Variables
This paper provides simple graphical criteria and semiparametric estimators that bridge the gap between identification and estimation for causal effects involving a single treatment and a single outcome.
On efficient adjustment in causal graphs
A novel, more intuitive graphical characterisation is given that the O-set is the parent set of the outcome node(s) in a suitable latent projection graph, which is called the forbidden projection, making it a useful methodological tool in its own right.
Efficient adjustment sets in causal graphical models with hidden variables
It is shown that if either no variables are hidden or if all the observable variables are ancestors of either treatment, outcome, or the variables that are used to decide treatment, a globally optimal adjustment set exists.
Efficient Least Squares for Estimating Total Effects under Linearity and Causal Sufficiency.
Recursive linear structural equation models are widely used to postulate causal mechanisms underlying observational data. In these models, each variable equals a linear combination of a subset of the
Graphical criteria for efficient total effect estimation via adjustment in causal linear models
Covariate adjustment is a commonly used method for total causal effect estimation. In recent years, graphical criteria have been developed to identify all valid adjustment sets, that is, all
Efficient Adjustment Sets for Population Average Causal Treatment Effect Estimation in Graphical Models
It is shown that if there exists an identifying formula for an interventional mean that depends only on treatment, outcome and mediators, then the non-parametric optimally adjusted estimator can never be globally efficient under the causal graphical model.
Alternative Graphical Causal Models and the Identification of Direct E!ects
This paper analyzes various measures of the ‘direct’ causal effect, focussing on the pure direct effect (PDE), and introduces the Minimal Counterfactual Model (MCM) which is referred to as ‘minimal’ because it imposes the minimal counterfactual independence assumptions.

A new class of hyper‐graphs, called mDAGs, are introduced and it is shown that each distinct marginal of a DAG model is represented by at least one DAG and graphical results towards characterizing equivalence of these models are provided.
Comment: Graphical Models, Causality and Intervention
I will focus on the connection between graphical models and the notion of causality in statistical analysis, and supplement the discussion with an ac'count of how causal models and graphical models are related.
Mendelian randomization as an instrumental variable approach to causal inference
This framework allows us to address limitations of the Mendelian randomization technique that have often been overlooked in the medical literature and suggests using directed acyclic graphs to check model assumptions by visual inspection.
