Constructing a Control Group Using Multivariate Matched Sampling Methods That Incorporate the Propensity Score
(American Statistical Association, 1985)Matched sampling is a method for selecting units from a large reservoir of potential controls to produce a control group of modest size that is similar to a treated group with respect to the distribution of observed ... -
Misunderstandings between Experimentalists and Observationalists about Causal Inference
(Wiley-Blackwell, 2008)We attempt to clarify, and suggest how to avoid, several serious misunderstandings about and fallacies of causal inference. These issues concern some of the most fundamental advantages and disadvantages of each basic ... -
Outcome-free Design of Observational Studies: Peer Influence on Smoking
(JSTOR, 2008)For estimating causal effects of treatments, randomized experiments are appropriately considered the gold standard, although they are often infeasible for a variety of reasons. Nevertheless, nonrandomized studies can and ... -
Propensity score methods for creating covariate balance in observational studies
(Elsevier BV, 2011)Randomization of treatment assignment in experiments generates treatment groups with approximately balanced baseline covariates. However, in observational studies, where treatment assignment is not random, patients in the ... -
Testing treatment effects in unconfounded studies under model misspecification: Logistic regression, discretization, and their combination
(Wiley-Blackwell, 2009)Logistic regression is commonly used to test for treatment effects in observational studies. If the distribution of a continuous covariate differs between treated and control populations, logistic regression yields an ...
