Do you know of any references that verify the accuracy of R for basic statistical calculations and tests. The results of these studies should indicate that R results are the same as the results of other statistical packages to a certain number of decimal places on some benchmark calculations.

Hi people, I need to prove the good quality of numerical accuracy of R. Anyone knows a paper or anything else comparing R to other statistical softwares in terms of numerical accuracy. I've made a long search about that but I found nothing. Please help me!! Thanx, Talita Leite ------------------------------------------------- Este e-mail foi enviado pelo Webmail da UFAL IMP:

...ersions. These do not cover R specifically, but do address S-Plus and SAS. This is not an exhaustive list by any means, but many of the papers do have other references that may be of value. 1. http://www.stat.uni-muenchen.de/~knuesel/elv/accuracy.html 2. http://www.amstat.org/publications/tas/mccull-1.pdf 3. http://www.amstat.org/publications/tas/mccull.pdf 4. http://www.npl.co.uk/ssfm/download/documents/cmsc06_00.pdf Another option is that NIST has reference datasets available for comparison at: http://www.itl.nist.gov/div898/strd/ These would allow you to conduct your own comparisons...
