Propensity Score Analysis Graphics A collection of functions that primarily produce graphics to aid in a Propensity Score Analysis (PSA). Functions include: cat.psa and box.psa to test balance within strata of categorical and quantitative covariates, circ.psa for a representation of the estimated effect size by stratum, loess.psa that provides a graphic and loess based effect size estimate, and various balance functions that provide measures of the balance achieved via a PSA in a categorical covariate. Software Depends: R (>= 2.14.0), rpart James E. Helmreich <James.Helmreich@Marist.edu> James E. Helmreich <James.Helmreich@Marist.edu> and Robert M. Pruzek <RMPruzek@yahoo.com>. We are grateful to KuangNan Xiong for significant work on the functions new to version 2.0: cstrata.psa, cv.bal.psa, and cv.trans.psa.
