The Chicago Chapter of the American Statistical Association is happy to announce that it will present a half-day workshop on CART (Classification and Regression Trees) conducted by Dr. Dan Steinberg Salford Systems and San Diego State University CART methodology concerns the use of tree structured algorithms to classify data into discrete classes. The terminology was invented by Breiman, et. al., in the early 1980's. The technique has found uses in both medical and market research statistics. For example, one tree structured classifier uses blood pressure, age and sinus tachycardia to classify heart patients as either high risk or not. Another might use age related variables and other demographics to decide who should appear on a mailing list. There will be other examples from both fields discussed in the workshop. Dr. Steinberg is Professor of Economics at San Diego State University and President of Salford Systems. He holds a Ph.D. degree in Economics from Harvard and has held positions at both the University of California at San Diego and San Diego State. He is the leader of the team that ported the original version of CART to the PC. He is well known for his previous work on statistical methods in economics and especially for his work on logistic regression.

This is a difficult area with many unsolved problems that appear regularly in recreational mathematics journals. Do you have a specific question or are you just looking for references? Aaron C.

It has been many years since I studied statistics and I haven't kept up. Today I've come across a term for which I simply don't know the meaning and which isn't found in any of my (old, hopelessly outdated?) texts. "Bootstrapping was used to estimate standard errors and to construct confidence intervals." Did they generate an estimate by subsampling the sample? Can anyone help with the definition of "bootstrap" in this context? -------------------------------------------:---------------------------- Patrick Wallace 504-928-9798 : You're born with nothing Scriptwriter (WGA) : and die with nothing.
