New versions 2.3 of our distr-family of packages are now available on CRAN.

(i.e.; startupmsg, SweaveListingUtils,

       distr, distrEx, distrDoc, distrEllipse,
       distrMod, distrSim, distrTEst, distrTeach)

Most importantly, we have included:

+ a quasi-MC trick by Nataliya Horbenko to better produce
  image distributions under complicated, not necessarily   monotone transformations
+ enhanced function qqplot
+ (enhanced) support for GEV distribution
+ new functional kMad
+ as well as several bug fixes

For more details see the corresponding NEWS files (e.g. news(package = "distr")
or using function NEWS from package startupmsg i.e. NEWS("distr")).

We are looking forward to getting your RFEs, bug reports or simple feedback,

Best,

Peter, Matthias, Nataliya



New versions 0.8 of our RobASt-family of packages are now available on CRAN.

(i.e.; RandVar, RobAStBase, ROptEst,

       RobLox, ROptEstOld, ROptEstTS, RobRex,
       RobLoxBioC)

Most importantly, we have included:

+ a quasi-MC trick by Nataliya Horbenko to better produce
  random variables under complicated not necessarily   monotone transformations

+ enhanced functions

   infoPlot, (plots relative information used for coordinates

              of a parameter estimator)
   ddPlot, (distance-distance plot)
   cniperPointPlot, (cniper concept for seemingly harmless

            contamination behavior)
   qqplot (now gets outlier corrected versions)

+ new risks: asAnscombe, asL1, asL4

  for asymptotic L1 L4 risk, and optimal bias robust estimator,    to given efficiency loss in ideal model

+ new helper methods makeIC

  to apply to functions or list of functions   for easily producing (suboptimal) ICs

+ new function getReq for two ICs IC1 and IC2
  to compute a radius interval where IC1 is better   than IC2 acc. to G-Risk

+ new function getMaxIneff() to compute,
  for any IC of class 'IC', the maximal inefficiency   for radius r varying in [0,Inf)

+ as well as several bug fixes

For more details see the corresponding NEWS files (e.g. news(package = "RobAStBase")
or using function NEWS from package startupmsg i.e. NEWS("RobAStBase")).

We are looking forward to getting your RFEs, bug reports or simple feedback,

Best,

Peter, Matthias, Nataliya
