Sabre

Sabre concentrates on procedures for estimating random and fixed effect models, it only has a few commands for performing simple transformations. For instance it does not have the facilities for handling data with missing values, reshaping data, or manipulations like sort on a particular variable, so these activities are best performed in more general statistical software packages.

 

These notes are not meant to be comprehensive as there are many sites that provide an introduction to Stata and some of the commands we present here, see for e.g. http://www.ats.ucla.edu/stat/stata/ .
