Multivariate analysis

Er... I would suggest that you move this question to the Science and Mathematics forum.

Can't help you but when I did some statistical work as part of my so-called education I was advised to get the appropriate software to do quantitative and qualitative analyses of data (mainly because I am mathematically challenged). As part of that quest I found heaps of websites dealing with the issues, some of them had freeware which worked fine. I'm sorry, I don't have the bookmarks, that was about fourteen computer crashes ago.
