Let me know if there are any questions regarding the algorithms or the statistics. I was pretty busy lately (and still am :-( ), but I would try to free some time to solve the problem if there is one.

Re: [sc-dev] stable algorithm for statistic functions issue 78250
Hi, Accessing CVS is not really a problem nowadays. Download one of the freely available IDEs (like Netbeans, Eclipse) and your are only away a few clicks from the source and patch tools. Eclipse even provides an specialized download for C++-Developers (CDT [1] & [2]) I'm not sure aboute netbeans but I think it also provides such a beast :-) Tom [1] http://www.eclipse.org/downloads/ [2] http://cdtdoug.blogspot.com/2007/06/introducing-cdt-for-windows.html Regina Henschel schrieb: Hello Eike, Eike Rathke schrieb: Hi Regina, On Thursday, 2007-07-05 10:34:37 +0200, Regina Henschel wrote: For COVAR it looks like this (based on OOF680_m18): Very nice, indeed.
