Forum: RobASt release 1.1
Posted by: Peter Ruckdeschel
Content: Updates for the packages of the RobASt family are now avaialable on CRAN inversion >= 1.1.0 Most importantly, we have (finally) released on CRAN a (long announced) new package "RobExtremes" in the RobASt family of packages. + It provides (speeded up) optimallyrobust estimators [MBRE, OMSE, RMXE] for Generalized Extreme Value [GEV] distributions, Generalized Pareto distributions [GPD], Pareto distributions, + As other examples of L2 differentiable Scaleshape families, it also provides these (speeded up) estimators for Weibull and Gamma distributions. + It has robust (highbreakdown) starting estimators for  GPD (PickandsEstimator, medkMAD, medSn, medQn)  GEV (PickandsEstimator)  Pareto (CramérvonMisesMinimumDistanceEstimator)  Weibull (the quantile based estimator of Boudt/Caliskan/Croux) + For all these families, of course, MLEs and MinimumDistanceEstimators are also available through package distrMod + We bridge to the diagnostics provided by package ismev, i.e. our return objects can be plugged into the diagnostics of this package + We have the usual diagnostic plots from package RobAStBase, i.e.  Outylingness plots  IC plots  Information plots  compareIC plots  Cniperpoint plots (from ROptEst) but also (adopted from package distrMod)  qqplots (with confidence bands)  returnlevel plots + As a starting point you may look at the included script "RobFitsAtRealData.R" in the scripts folder of the package, accessible by file.path(system.file(package="RobExtremes"), "scripts/RobFitsAtRealData.R") This is joint work with Nataliya Horbenko (whose PhD thesis went into this package to a large extent), nataliya.horbenko@gmail.de, with contributions by Dasha Pupashenko, Misha Pupashenko, Gerald Kroisandt, Eugen Massini, Sascha Desmettre and Bernhard Spangl in the framework of project "Robust Risk Estimation" (20112016) funded by Volkswagen foundation (and gratefully ackknowledged). Thanks also goes to the maintainers of CRAN, in particully to Uwe Ligges who greatly helped us with finding an appropriate way to store the database of interpolating functions which allow the speed up  this is now package RobAStRDA on CRAN.
