From datasets to framesets and alias variables: Data management advances in Stata

The aim of this blog is to describe two novel features introduced in Stata 18 (released in 2023): 1) framesets and 2) alias variables across frames. These features enable Stata to deal with a multiplicity of potentially very large datasets efficiently and conveniently. Framesets allow you to bundle, save on file, and load in memory a set of related frames that hold datasets. Alias variables allow you to access variables in other frames as if they were part of the current frame, with very little memory overhead. Read more…
