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.



I have been asked by a friend to do a bootstrap analysis in STATA for
confidence intervals (which i do know how to do). However, he is also
asking for a cross validation, and to be honest I am a bit stuck as to
what exactly he means by this.
