Package: vecmatch Title: Generalized Propensity Score Estimation and Matching for Multiple Groups Version: 1.3.0.9000 Authors@R: person("Mateusz", "Kolek", , "mati.kolek13@gmail.com", role = c("aut", "cre", "cph"), comment = c(ORCID = "0000-0001-6470-4830")) Description: Implements the Vector Matching algorithm to match multiple treatment groups based on previously estimated generalized propensity scores. The package includes tools for visualizing initial confounder imbalances, estimating treatment assignment probabilities using various methods, defining the common support region, performing matching across multiple groups, and evaluating matching quality.
