datacheck is a simple utility for carrying out data checks and reporting on problems or errors in a dataset. A datacheck statement specifies a condition which one or more variables in the dataset must meet. If the data 'fail' the check, the program displays meaningful and customizable output identifying the problem observation(s). In contrast to assert, datacheck does not halt Stata or produce any errors, so a number of datacheck statements can be included in a do-file to run in sequence. This allows a suite of data checks to be performed in a single run, with the customized output serving as a user-friendly log detailing problems with the data.

This module should be installed from within Stata by typing "ssc install datacheck". Windows users should not attempt to download these files with a web browser.
