Building a Propensity Score Model with SAS/STAT® …

Propensity score matching is an intuitive approach that is often used in estimating causal effects from observational ... possible to obtain unbiased estimates of a treatment’s causal effect by using methods that properly adjust for the confounders X. For more information about the definition of causal effects in a potential outcome ...

The propensity score would then be the predicted probability of receiving the treatment. Propensity scores are being used in observational studies to reduce bias. Three commonly used techniques are subclassification on the propensity score, regression adjustment using the propensity score, and case-control matching on the propensity score.

Why Propensity Scores Should Not Be Used for Matching

Rubin,1984), and some uses of the propensity score within other methods (e.g. Diamond and Sekhon,2012; Imai and Ratkovic,2014). Moreover, the mathematical theorems in the literature used to justify propensity scores in general, such as in Paul R. Rosenbaum and Rubin (1983), are of course correct and useful elsewhere, but we show they are not

Introduction to Regression Models for Panel Data Analysis ...

Oct 07, 2011 · using cross-sectional data collected at fixed periods of time generally use dummy variables for each time period in a two-way specification with fixed-effects for time. Are the data up to the demands of the analysis? Panel analysis is data-intensive. Are two waves enough? Can you perform the necessary specification tests?
