The output provided by most Stata commands is a plain text not suitable to be presented or published. After the numerical output is obtained, the user has to copy it in a word processor to complete the editing process. Some Stata commands help you to obtain well formatted output, expecially tabulating results in LaTex or other formats, but they are not a complete solution and they are not friendly tools. Stata automatic report (Sar) is an easy to use macro for Microsoft Word for Windows which allows a powerful integration between Stata and the word processor by Microsoft. Using Sar the user can retrieve numerical results from Stata and automatically insert them in a well formatted Word document, exploiting all the functions of Word. This process in managed by Word while Stata is executed in background. Sar requires Stata commands and some specific Sar commands to be written in ordinary Word comments. So the report is well documented and this can encourage the sharing of the workflow of data anlysis and the reproducibility of the research. Using Sar the user can create an automatic report, i.e. a Word document that can be automatically updated if data have changed. Sar works only on Windows systems.
