I am just giving it a wild guess, I had not seen that in SQL Server atleast. Lets if someone knows about it. Otherwise what you can do is create a dot net assembly (CLR assembly). I guess it should be there in dot net library. Hope this helps.

I also need to implement the Excel Linest() function in SQl server 2008.

not offhand, sorry; i only looked briefly at teh psot i showed you, and would have to read up on it;

it really does sound like soemthing i'd put into a CLR instead though.

i found theis link that implies they have a CLR for Linest / liniar regression:http://westclintech.com/XLeratorDBstatisticsDocumentation/tabid/159/Default.aspx

will that do teh job?
