FAQ
How do I calculate R-squared using these tools?
Input your observed and predicted values or upload your dataset through the browser interface. The calculations are processed on our servers to determine the coefficient of determination (R-squared) without requiring any software installation.
Are my datasets and statistical inputs stored?
No. Text inputs are not stored on our servers, and any uploaded data files are automatically and permanently deleted after 6 hours.
Can I calculate adjusted R-squared as well?
Yes, our tools support calculating both standard R-squared and adjusted R-squared to help you accurately evaluate regression models with multiple predictors.
