I would be grateful for some direction to the area in the stata manual that explains how to do the following
I am trying to split a dataset (n ~1500) into an estimation sample and a validation sample by random sampling (n = 400-500) from the dataset

Later I wish to compare results with that using bstrap techniques
Thanks in advance
