Graphical MCPs include many commonly used procedures as special cases; see Bretz et al. (2011) <doi:10.1002/bimj.201000239>, Lu (2016) <doi:10.1002/sim.6985>, and Xi et al. (2017) <doi:10.1002/bimj.201600233>. This package is a low-dependency implementation of graphical MCPs which allow mixed types of tests. It also includes power simulations and visualization of graphical MCPs.https://github.com/r-universe/openpharma/actions/runs/38211418732Mon, 12 Oct 2026 01:42:12 GMTgraphicalMCP0.3.0.9000successhttps://openpharma.r-universe.devhttps://github.com/openpharma/graphicalmcpgraph-examples.Rmdgraph-examples.htmlCommon multiple comparison procedures illustrated using graphicalMCP2024-01-23 20:28:262026-08-21 16:38:48graphicalMCP.RmdgraphicalMCP.htmlGet started2024-01-23 20:28:262026-08-21 16:38:48glossary.Rmdglossary.htmlGlossary2024-01-23 20:28:262024-02-12 21:28:07closed-testing.Rmdclosed-testing.htmlGraphical multiple comparison procedures based on the closure principle2024-01-23 20:28:262024-06-04 16:12:16group-sequential-testing.Rmdgroup-sequential-testing.htmlGroup Sequential Design with Graphical Approaches2026-08-21 16:38:482026-08-26 19:55:34internal-validation.Rmdinternal-validation.htmlPower simulations using multiple approaches for internal validation2025-05-06 21:52:562025-05-06 21:52:56shortcut-testing.Rmdshortcut-testing.htmlSequentially rejective graphical multiple comparison procedures based on Bonferroni tests2024-01-23 20:28:262026-08-21 16:38:48gsd-validation.Rmdgsd-validation.htmlValidation of Group Sequential Functions Against gsDesign and rpact2026-08-21 16:38:482026-08-21 16:38:48
