Matching and Propensity Scores
The popularity of matching techniques has increased considerably during the last decades. They are mainly used for matching treatment and control units in order to estimate causal treatment effects from observational studies or for integrating two or more data sets that share a common subset of covariates. In focusing on causal inference with observational studies, we discuss multivariate match...
متن کاملPropensity Score Matching for Multiple Treatments Comparison in Observational Studies
A major limitation of making inference about treatment effect based on observational data from a non-randomized study designs is the treatment selection bias, in which the baseline characteristics of population under one treatment could dramatically differ from the other one. If not handle properly, such sources of heterogeneity will introduce confounding effect into causaleffect relationship a...
متن کاملMatching with Propensity Scores to Reduce Bias in Observational Studies
In observational studies subjects are not randomly assigned to treatment and control groups. Therefore, both groups can be significantly different from each other and their differences after applying a treatment cannot be attributed to the treatment effect. Propensity scores methods offer a way to balance groups by matching treatment and control units based on a set of covariates. This paper ex...
متن کاملRare Outcomes, Common Treatments: Analytic Strategies Using Propensity Scores
Propensity Scores When treated patients are compared to controls, differing outcomes may reflect either effects caused by the treatment or differences in prognosis before treatment. Random assignment of patients to treatment or control, as in a randomized, controlled clinical trial (1), ensures that the groups were comparable before treatment and the prognosis in treated and control groups was ...
