Has Stata thought about this any more? Especially, might CART be a possibility in Stata within the next year?

Does anyone know of a CART-type package for Stata.


Nick Cox replied:

CART -- usually I think regarded as an abbreviation of
Classication and Regression Trees, after the monograph
by Breiman, Friedman, Olshen and Stone -- has been requested
several times as an addition to official Stata, including
at the NASUG meeting in Boston on March 17. The Stata
Corp response is in essence "We'll think about it".

Fred Wolf added:

Some listers might be interested in the commercial package called "CART" and sold by Salford Systems at a reasonable cost. It has been the major CART package for almost 2 decades. Recently, CART has been seen as a "data mining" tool by Salford systems. This has led to increases in prices to levels in excess of thousands of dollars for new purchases as well as to timed licenses. The next most convenient approach to CART is through S-plus.


I add:

In her review with example in"Classification and Regression Tree Analysis in Public Health: Methodological Review and Comparison with Logistic Regression," Stephanie Lemon, et al, uses "The C&RT analysis was conducted using Answer Tree 2.0, a product of SPSS."

But I'd like to use Stata.

Thank you.
