ANNEX I – Stata Commands
This annex provides a brief reference guide and to explain the various functions of the Stata commands
most commonly used. This annex was developed by Ellen Payongayong. The commands in the table
below do not contain the full Stata syntax.
Note that commands can be abbreviated. In the Help Syntax Viewer, the syntax explanation will show
how much of the command must be typed, e.g. “Summarize” can be shortened to “su” or “sum”. In
this Help viewer, the letters that are required for the command are underlined.
