PSAgraphics: 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.
