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?
