Hi,

The paper

@ARTICLE{AlmironSilvaMM:2009,
  author = {Almiron, M. and Almeida, E. S. and Miranda, M.},
  title = {The Reliability of Statistical Functions in Four Software Packages
	Freely used in Numerical Computation},
  journal = {Brazilian Journal of Probability and Statistics},
  year = {in press},
  volume = {Special Issue on Statistical Image and Signal Processing},
  url = {http://www.imstat.org/bjps/}}

is freely available under the "Future Papers" link. It makes a nice
comparison of the numerical properties of R, Ox, Octave and Python.

Thanks for posting this. I?m happy to see that the results for R were 
generally excellent, and almost always better than for the three other 
software packages.

But there were a few cases where R did not turn out to be the winner.
Rather surprising that Ox was better than R for computing the 
autocorrelation coefficient for two of the datasets, given its terrible 
results for the standard deviation. Anybody have any ideas why?
