Causal Inference from Complex Longitudinal Data

  title={Causal Inference from Complex Longitudinal Data},
  author={James M. Robins},
The subject-specific data from a longitudinal study consist of a string of numbers. These numbers represent a series of empirical measurements. Calculations are performed on these strings of numbers and causal inferences are drawn. For example, an investigator might conclude that the analysis provides strong evidence for “a direct effect of AZT on the survival of AIDS patients controlling for the intermediate variable - therapy with aerosolized pentamidine.” The nature of the relationship… 
Causal Reasoning from Longitudinal Data *
Abstract.  This paper reviews some of the key statistical ideas that are encountered when trying to find empirical support to causal interpretations and conclusions, by applying statistical methods
Causal inference for complex longitudinal data: the continuous case
Robins’ theory of causal inference for complex longitudinal data is extended to the case of continuously varying as opposed to discrete covariates and treatments and it is shown that assumptions concerning counterfactual variables place no restriction on the joint distribution of the observed variables.
▪ Abstract When experimental designs are infeasible, researchers must resort to the use of observational data from surveys, censuses, and administrative records. Because assignment to the independent
Causal effects in clinical and epidemiological studies via potential outcomes: concepts and analytical approaches.
An approach to making inferences about the causal effects of treatments or agents via potential outcomes is reviewed, where the causal effect is defined as a comparison of results from two or more alternative treatments, with only one of the results actually observed.
A Bayesian approach to the g-formula
It is shown that the frequentist properties of the Bayesian g-formula suggest it improves the accuracy of estimates of causal effects in small samples or when data are sparse, and adopted the language of potential outcomes under Rubin's original Bayesian framework.
Confounding Equivalence in Causal Inference
The test for deciding, from a given causal diagram, whether two sets of variables have the same bias-reducing potential under adjustment is extended to include treatment-dependent covariates by broadening the back-door criterion and establishing equivalence of adjustment under selection bias conditions.
Estimation of the Causal Effect of a Time-Varying Exposure on the Marginal Mean of a Repeated Binary Outcome
We provide sufficient conditions for estimating from longitudinal data the causal effect of a time-dependent exposure or treatment on the marginal probability of response for a dichotomous outcome.

This paper reviews the state of the art in identification of causal effects and related counterfactual quantities in the framework of graphical causal models, a formalism where a causal domain of interest is represented by directed acyclic graphs with vertices representing variables of interest, and arrows representing direct causal influences.
Targeted Maximum Likelihood Based Causal Inference
Given causal graph assumptions, intervention-specific counterfactual distributions of the data can be defined by the so called G-computation formula, which is obtained by carrying out these


Causal diagrams for empirical research
SUMMARY The primary aim of this paper is to show how graphical models can be used as a mathematical language for integrating statistical and subject-matter information. In particular, the paper
Correcting for non-compliance in randomized trials using structural nested mean models
In a randomized trial designed to study the effect of a treatment of interest on the evolution of the mean of a time-dependent outcome variable, subjects are assigned to a treatment regime, or,
Causation, prediction, and search
The authors axiomatize the connection between causal structure and probabilistic independence, explore several varieties of causal indistinguishability, formulate a theory of manipulation, and develop asymptotically reliable procedures for searching over equivalence classes of causal models.
The central role of the propensity score in observational studies for causal effects
Abstract : The results of observational studies are often disputed because of nonrandom treatment assignment. For example, patients at greater risk may be overrepresented in some treatment group.
Estimation of the time-dependent accelerated failure time model in the presence of confounding factors
The purpose of this paper is to provide conditions under which it would be possible to estimate the causal effect of a time-dependent treatment or exposure on time to an event of interest in the presence of time- dependent confounding covariates and to construct estimators for the treatment effect under these conditions.
Conditional Permutation Tests and the Propensity Score in Observational Studies
Abstract In observational studies, the distribution of treatment assignments is unknown, and therefore randomization tests are not generally applicable. However, permutation tests that condition on
A Theory of Inferred Causation
A note on the covariance of the Mantel-Haenszel log-odds-ratio estimator and the sample marginal rates.
A simple technique is used to approximate cov(theta MH, pi), i = 1, 2, where theta MH is the Mantel-Haenszel log-odds-ratio estimator for a 2 x 2 x K table and the pi are the sample marginal proportions.
