In addition to the official subversion repository we now also maintain a read-only repository mirror on
google code, mainly as a fail-over
backup solution if something happens to the primary server, but also because it provides
additional ways to access the source: Subversion over the HTTP protocol (useful if you're behind a restrictive firewall), and
source code browsing
directly in the web browser.
Official Subversion Repository:
svn://svn.opensourcedotnet.info/mathnet/trunk
New Subversion Repository Mirror:
http://mathnet-mirror.googlecode.com/svn/trunk/
Of course the official/primary repository remains accessible anonymously as well.

The algorithm on how the Mean, Variance and Sigma are incrementally computed in the statisics accumulator (MathNet.Numerics.Statistics.Accumulator) has been improved last week in Iridium revision 503 to provide better numeric stability when dealing with samples with a very large mean but only a small variance.
For example, the variance of normally distributed samples with mean 10^9 but a variance of only 1 can now be accurately estimated. The previous implementation has been very unstable in that case.
The new algorithm continues to support removing samples from the accumulator (and updates the estimates accordingly).
