st: cross validation and student version of STATA "Sophie Barthel"

[David Airey <david.airey@Vanderbilt.Edu>]

In some contexts, cross-validation means to develop a predictive model 
in one "training" data set and use it in an independent data set to 
'validate' the predictive ability of the model. This reminds me of the 
split-half coefficient or cronbach's alpha.
