Generally a duplicate of 20 or so observations from the dataset is sufficient to display your difficulty. See help dataex for details. As from Stata 15.1 (and 14.2 from 19 December 2017), dataex is included With all the Formal Stata distribution. End users of Stata fifteen (or fourteen) will have to update to take pleasure in this.

We see no matter whether variables are numeric or string, whether you might have price labels outlined and what is a consequence of a particular Display screen structure.
