Causal relationship and confounding in statistical models.
Randomized trials are designed to eliminate systematic error (bias) when estimating the effect of an intervention (usually a treatment) through randomized allocation of patients to treatment with concealment of allocation. In an observational study, no disturbance of the process of care takes place and the outcome is merely ‘observed’ along with other relevant information, such as patients’ pre...
متن کاملConfounding Equivalence in Causal Inference
The paper provides a simple test for deciding, from a given causal diagram, whether two sets of variables have the same bias-reducing potential under adjustment. The test requires that one of the following two conditions holds: either (1) both sets are admissible (i.e. satisfy the back-door criterion) or (2) the Markov boundaries surrounding the treatment variable are identical in both sets. We...

Studies have found positive correlations between affective states (e.g., confusion, boredom) and learning outcomes in educational technologies like ASSISTments and Carnegie Learning's Cognitive Tutor. The adage that "correlation does not imply causation" is especially apt in light of these observations; it seems counterintuitive that increasing student boredom or confusion (e.g., designing syst...
متن کاملEstimating Causal Effects by Bounding Confounding
I Assessing the causal effect of a treatment variable X on an outcome variable Y from observational data is usually difficult due to the possible existence of unobserved common causes. I In our paper we examine how, given an observed dependence between X and Y , various kinds of additional assumptions which related to the “strength” of confounding of X and Y can help to estimate the causal effe...
