A quick look at paragraph 9.10 of (Harrell 2001) 
suggest to me that that contains most of the 
information you need to implement such a method in 
Stata. It is very similar to the way Jay suggested.
	
Harrell, Frank (2001) "Regression Modeling Strategies:
With Applications to Linear Models, Logistic 
Regression, and Survival Analysis", New York, Springer.

Hope this helps,
Maarten
