Changes in version 1.7 (2026-03-25) - Restore the suggestion of the package CoxBoost and the corresponding functions that were removed, as this package is again on the CRAN. - New public wrappers for penalized, glmnet, grpreg, SGL, ncvreg, randomForestSRC, and mboost Changes in version 1.6 (2025-09-15) - Maintainer email update - Added unit tests - Fix package to get rid of CRAN check notes - Add package doi Changes in version 1.5 (2023-03-22) - Code update to fix CRAN issues. Changes in version 1.4 (2022-03-03) - Code update. Changes in version 1.3 (2021-03-16) - Added github actions, pkgdown site, readme.Rmd and package logo. Changes in version 1.2 (2021-02-27) - Suggestion of package CoxBoost and corresponding functions removed, as this package was archived. Changes in version 1.1-7 (2013-04-08) - Suggestion of package randomSurvivalForest resolved, as this package was archived. Changes in version 1.1-6 (2011-03-16) - bug concerning weighting in censored competing risks situation in function pmpec() fixed Changes in version 1.1-5 (2010-01-22) - Bug in function pmpec() fixed (error message for argument type="NoInf") Changes in version 1.1-4 (2009-09-28) - New peperr() arguments 'sr', 'sr.name' and 'sr.restore' to allow for restoring previously saved results - Incorporation of interface to package randomSurvivalForest: Functions fit.rsf_mtry, complexity.ipec.rsf_mtry allow for selection of number of candidate values at each node by IPEC Changes in version 1.1-3 (2009-04-23) - New function ipec(), to caclulate the integrated prediction error curve for survival data Changes in version 1.1-2 (2009-01-22) - Default value of peperr argument RNG changed to 'RNGstream' - New peperr() argument lb, to choose if computation on slaves should be executed load balanced Changes in version 1.1-1 (2008-12-18) - Independent parallel random number streams integrated -> new peperr() argument RNG - peperr_1.1.tar.gz contained peperr_1.0-3.tar.gz by mistake - plot.peperr() now works for non-integer complexity values as well Changes in version 1.1 (2008-10-28) - New arguments of function peperr() are 'clustertype', to specify the type of cluster to be used ('SOCK' for socket, 'MPI', 'PVM' or 'NWS') and 'clusterhosts', that specifies the host list for socket clusters, if 'clustertype=SOCK' or 'clustertype=NWS'. - Function extract.fun() returns additional list element 'variables', containing global variables required for computation on cluster nodes. - Default of argument 'parallel' in function peperr() changed from 'FALSE' to 'NULL'. This fixed bug that switching from parallel to sequential execution was not possible, but is not affecting any other cases. Changes in version 1.0-3 (2008-09-02) - New argument 'seed' in function peperr(), to allow reproducibility in parallel execution Changes in version 1.0-2 (2008-08-07) - Bug fixed which occurred in competing risks setting Changes in version 1.0-1 (2008-07-29) - predictProb() functions require arguments 'response' and 'x' instead of 'data' Changes in version 1.0 (2008-07-16) - initial public release
