Dear All, I am looking for large data sets for regression analysis (not for classification)- in fact I would like to compare a new idea for decision trees with some well-known procedures. I have several good data sets (millions of obs and thousand of predictors), but all of them are similar (prediction of next year health care cost) and I need more variety. The web sites I checked out (UCI; KDD Cup etc) did not have what I need: real/generated data for regression analysis with at least 5-10,000 observations (more better) and 20+ predictors (more better). It would be great if some of you give me a link to download such data sets or idea where I could find them.
Thank you in advance Ogi -- Ognian Asparouhov, Ph.D. Senior Scientist AI Insight, Inc. Orlando, Florida
