Covariance Adjustment in Randomized Experiments and Observational Studies
By slightly reframing the concept of covariance adjustment in randomized experiments, a method of exact permutation inference is derived that is entirely free of distributional assumptions and uses the random assignment of treatments as the “reasoned basis for inference.” This method of exact permutation inference may be used with many forms of covariance adjustment, including robust regression...
متن کاملAttributable E¤ects in Randomized Experiments and Observational Studies
The motivation for randomization inference and sensitivity analysis is reviewed. New methods are discussed for inverting randomization tests to provide interval estimates of the magnitude of treatment e¤ects. 1 Notation and Review
متن کاملRandomized Experiments and Observational Studies: Causal Inference in Statistics
This talk describes the theory of causal inference in randomized experiments and nonrandomized observational studies, using two simple theoretical/actual examples for illustration. Key ideas: causal effects, randomized experiments, adjustments for observed covariates, sensitivity analysis for unobserved covariates, reducing sensitivity to hidden bias using design strategies. 1. Seven Key Contri...
متن کاملPropensity Score Adjustment for Unmeasured Confounding in Observational Studies
Adjusting for several unmeasured confounders is a challenging problem in the analysis of observational data. Information about unmeasured confounders is sometimes available from external validation data, such as surveys or secondary samples drawn from the same source population. In principal, the validation permits us to recover information about the missing data, but the difficulty is in elici...
