Quick Tips

This archive includes the complete list of user-written Stata packages till January 1st 2015 and includes a brief description and HTML help file. This archive has been created for education purpose (not for installing packages!), particularly for those who wish to find interesting packages or study a user-written package as quick as a mouse click. The archive includes several useful features such as providing HTML help files as well as categories that indicate what kind of Stata programming files (ado, mata, plugin, dlg, tut, scheme, style) are included in each package. In addition, literate package - packages that comment the procedure and structure of the ado files - are specified with a red circle and are excellent materials for learning/improving Stata programming.

Introduction

Using the findit command, Stata can search and install user-written Stata packages on your machine. But why do we need an archive for searching through packages, viewing them on ado and the help files online, and downloading them? My main argument is that user-written Stata packages are the source of learning advanced Stata programming. In general, any program - whether it is written by Stata staff or a Stata user - intends to solve a problem or facilitate a task. While other users can get benefit from using the program, reading the source code can reveals how the problem was solved. But I have had other reasons for spending the entire 2014 Christmas and New Years' holidays, working full-time on this archive which are:

  • Creating online archive that allows people to search for a keywork across all user-written packages and quickly read the description of each package
  • Categorize the packages into separate archives based on the type of files used in their packages
  • Attach the online help file for each package that people can read on their web-browser
  • Allow the users to read the Ado source code on their web browser or download it
  • Allow the users to download packages that include more than one program file
  • Encourage Stata programmers to comment their programs and share their knowledge within their Stata packages

This archive receives monthly update at the end of each month, based on the latest updates on SSC server. If your package is not included in this archive, please add comments to your programs (i.e. describe the procedure, the more you explain the more generous you are) and submit the files to haghish[at]imbi.uni-freibourg[dot]de


Color codes

Different colors are used to categorize the packages. Blue text color indicates that the package includes only one ado file and can be viewed on your web-browser. Pink text color indicates that the package includes several files which will be downloaded as a zip file and cannot be viewed on your web-browser. Color circles are used to indicate what type of programs are included in the package which are listed below:

Purple circle indicates that the package includes .tut file which is Stata tutorial program. Read more...

Yellow circle indicates that the package includes Mata programming

Aquamarine circle indicates that the package has .dlg dialog box

Green circle indicates that the package has .plugin or programs/files written in another programming language

Gray circle indicates that the package has a Stata .scheme or a .style file

Red circle indicates that the package includes comments explaining the logic and procedure of the program. These packages can be used by Stata programming learners of all levels, based on the difficulty of the package. You can add comments to your packages and submit the files to haghish[at]imbi.uni-freibourg[dot]de
