Show abstract
This article introduces dqrep, a Stata package designed for conducting comprehensive data quality assessments. A single command call flexibly scales from small "on-the-fly" assessments involving only a few variables to extensive tasks, such as generating and comparing quality reports for thousands of variables across multiple examinations within or across studies. To do so, dqrep activates an analytical pipeline that evaluates the requested data quality aspects, such as data integrity, missingness, range violations, outliers, temporal trends, observer or device effects. Detailed information and expectations about the data can be provided via the numerous dqrep options or MS Excel sheets. The package generates single or series of reports in PDF and DOCX formats, detailing data properties as well as the type, number, and severity of data quality issues. In addition, HTML dashboards may be requested to browse images. dqrep offers standardized machine-readable result summaries, facilitating downstream tasks such as benchmarking data quality across studies and examinations. The package is online available from https://dataquality.qihs.uni-greifswald.de/vignettes.html#STATA
