Documentation

Academic guidance for statistical analysis, reporting, citation, and validation.

Introduction

StatClinic is a browser-based statistical analysis platform developed for clinical, biomedical, and health research. It combines guided statistical workflows, evidence-based test selection, automated assumption checking, publication-ready reporting, and research methodology guidance within a single integrated environment. StatClinic is designed to support researchers throughout the statistical analysis process, from selecting the appropriate statistical method to interpreting and reporting results according to international scientific standards.

StatClinic supports both guided and direct statistical analysis. Researchers may either follow a guided workflow that recommends the appropriate statistical method based on study design and data characteristics, or directly access individual statistical procedures when the required method is already known.

How to Cite StatClinic

When StatClinic is used for statistical analysis, interpretation, or reporting, cite the software version used. Auronile is the organization author for all StatClinic software citations.
