Causal Inference Lecture Notes: Causal Inference with Repeated Measures in Observational Studies
We start with the simple panel data of two waves and assume that the outcome variables are measured before and after the administration of the treatment. We use Y0i and Y1i to denote the observed outcomes for time 0 (pre-treatment) and time 1 (post-treatment). Finally, let Gi be the binary indicator variable which indicates the group membership of unit i (Gi = 1 for the treatment group and Gi =...
متن کاملA Comparative Review of Selection Models in Longitudinal Continuous Response Data with Dropout
Missing values occur in studies of various disciplines such as social sciences, medicine, and economics. The missing mechanism in these studies should be investigated more carefully. In this article, some models, proposed in the literature on longitudinal data with dropout are reviewed and compared. In an applied example it is shown that the selection model of Hausman and Wise (1979, Econometri...
متن کاملCausal inference from longitudinal studies with baseline randomization.
We describe analytic approaches for study designs that, like large simple trials, can be better characterized as longitudinal studies with baseline randomization than as either a pure randomized experiment or a purely observational study. We (i) discuss the intention-to-treat effect as an effect measure for randomized studies, (ii) provide a formal definition of causal effect for longitudinal s...
متن کاملCausal Inference for Complex Longitudinal Data: the continuous case
We extend Robins’ theory of causal inference for complex longitudinal data to the case of continuously varying as opposed to discrete covariates and treatments. In particular we establish versions of the key results of the discrete theory: the g-computation formula and a collection of powerful characterizations of the g-null hypothesis of no treatment effect. This is accomplished under natural ...
