Hi all, As happens from time to time, discussions on this list appear regarding the use of popular spreadsheets for statistical analysis. One such thread (post of mine) is here:
http://maths.newcastle.edu.au/~rking/R/help/03a/6326.html While not advocating such use, these discussions have referenced articles that provide independent reviews of these applications and issues of accuracy, etc. Based upon a posting to Linux Today (http://linuxtoday.com/news/2004022600226OSBZGN), I became aware this evening of a new paper by the well known B.D. McCullough, who has published many such reviews of both spreadsheets and other statistical applications. In the latest paper (pdf available from http://www.csdassn.org/software_reports.html), Prof. McCullough reviews Gnumeric as an example of how an open source project has responded to prior criticism of issues, while raising well known issues with Excel, at least through XP. He leaves open to further research, any improvements to Excel 2003. One lingering criticism is Gnumeric's RNG, however Prof. McCullough (who references Prof. Ripley's 1990 PRNG paper) indicates in this article that the Gnumeric team has incorporated the Mersenne Twister to a beta version of Gnumeric, which may already have been released by now. This modification ameliorates this concern. For those wishing to stay abreast of such issues, this new paper may be of interest. It puts the open source efforts of the Gnumeric team (http://www.gnome.org/projects/gnumeric/) in a very favorable light.
