A stratified Cox model and a singular value\ndecomposition are provided. The former makes direct use of code\nfrom the R 'survival' package. (That is, the underlying Cox\nmodel code is derived from that in the R 'survival' package.)\nSites may provide data via several means: CSV files, Redcap\nAPI, etc. An extensible design allows for new methods to be\nadded in the future and includes facilities for local\nprototyping and testing. Web applications are provided (via\n'shiny') for the implemented methods to help in designing and\ndeploying the computations.", "Copyright": "inst/COPYRIGHTS", "Encoding": "UTF-8", "License": "LGPL (>= 2)", "Roxygen": "list(markdown = TRUE)", "RoxygenNote": "7.3.3", "Config/pak/sysreqs": "cmake libgmp3-dev make libicu-dev libsodium-dev\nlibuv1-dev libssl-dev zlib1g-dev", "Repository": "https://bnaras.r-universe.dev", "Date/Publication": "2025-12-03 17:53:48 UTC", "RemoteUrl": "https://github.com/bnaras/distcomp", "RemoteRef": "HEAD", "RemoteSha": "42ffaf1d5f1e589bc9168594f73ff2d6cdfd3c68", "NeedsCompilation": "yes", "Packaged": { "Date": "2026-10-16 21:49:49 UTC", "User": "root" }, "Author": "Balasubramanian Narasimhan [aut, cre],\nMarina Bendersky [aut],\nSam Gross [aut],\nTerry M.
