[R] software comparison

[Robert McFadden]

Dear R Users,
May be you are interested in an article that compares 9 statistical
softwares (including R).
Any comments are appreciate.

Abstract
The reliabilities of nine software packages commonly used in performing
statistical analysis are assessed and compared. The
(American) National Institute of Standards and Technology (NIST) data sets
are used to evaluate the performance of these software
packages with regard to univariate summary statistics, one-way ANOVA, linear
regression, and nonlinear regression. Previous
research has examined various versions of these software packages using the
NIST data sets, but typically with fewer software
packages than used in this study. This study provides insight into a
relative comparison of a wide variety of software packages
including two free statistical software packages, basic and advanced
statistical software packages, and the popular Excel package.
Substantive improvements from previous software reliability assessments are
noted. Plots of principal components of a measure of
the correct number of significant digits reveal how these packages tend to
cluster for ANOVA and nonlinear regression.


Best,
Rob
