Bogdan Crivat - whom many of you know from sqlserverdatamining.com and the DM Forums has started his own data mining blog - with a first entry to answer many of the questions around "Excel does this and DM does that".  In this entry Bogdan discusses comparative regression accuracy between Excel and SQL Server Data Mining, and demonstrates the DMPREDICT cell function - an "undocumented feature" of the data mining addins for 2005, but supported in the upcoming 2008 version.

 

Enjoy!
