About the project
Web of Statistics was created by Dr. Silvio D. Rodríguez, Professor of Applied Statistics at the Pontificia Universidad Católica Argentina (UCA), Buenos Aires. The goal of the project is to make statistical tools more accessible for education, research and professional data analysis.
This is an academic and educational initiative. The tools are provided freely, and users are responsible for checking results and applying statistical methods appropriately.
Feedback, bug reports and suggestions are welcome. Please contact webofstatistics@gmail.com.
Donations help cover hosting and maintenance costs so the platform can remain free and ad-free.
