Data Analysis SOftware

[Nicholas D. Garigliano]

I'm looking for info on software for doing data analysis of 
cell based and ELISA type assays.  It would need to be able 
to perform various curve fits, spline, quadratic, 4-P etc., 
without extensive programing or macro making and provide 
relevant information about the curve.  I am I just wishing 
here or is there anyting out there??  Could you also replay 
to my e-mail as I'm buried with work and usually fall 
quickly behind on reading the news.  Thanks.
