Programming an estimation command in Stata: Global macros versus local macros

3 November 2015 2 comments

I discuss a pair of examples that illustrate the differences between global macros and local macros. You can view this post as a technical appendix to the previous post in the #StataProgramming series, which introduced global macros and local macros.

In every command I write, I use local macros to store stuff in a workspace that will not alter a user’s data and to make my code easier to read. A good understanding of the differences between global macros and local macros helps me to write better code. The essential differences between global macros and local macros can be summarized in two points. Read more…

Programming an estimation command in Stata: Where to store your stuff

27 October 2015 No comments

If you tell me “I program in Stata”, it makes me happy, but I do not know what you mean. Do you write scripts to make your research reproducible, or do you write Stata commands that anyone can use and reuse? In the series #StataProgramming, I will show you how to write your own commands, but I start at the beginning. Discussing the difference between scripts and commands here introduces some essential programming concepts and constructions that I use to write scripts and commands.

This is the second post in the series Programming an estimation command in Stata. I recommend that you start at the beginning. See Programming an estimation command in Stata: A map to posted entries for a map to all the posts in this series. Read more…
