Terms of use
Free to use, including commercially, and provided without warranty.
By using statcompute.com you agree to these terms. They are short because the site is simple: it is a set of free calculators, provided as-is.
What you may do
Use the calculators for anything — coursework, research, work, curiosity — including commercially. Results are yours. You may link to any page. You may quote a formula or an explanation with attribution and a link.
What you may not do
Republish the site's text wholesale, scrape it systematically, or present it as your own work. Do not attempt to interfere with the site's operation or with other people's use of it.
No warranty
The calculators are checked carefully against R and carry a test suite, and they are still provided without warranty of any kind. Statistical software can be wrong, statistical results can be misread, and a correct number applied to the wrong question is still the wrong answer. ZW Studio LLC accepts no liability for any loss arising from use of this site or reliance on its output. Verify anything consequential independently.
Not professional advice
Nothing here is medical, legal, financial or professional advice. Tools such as the odds ratio and relative risk calculators are general statistical instruments and are documented with non-medical examples; they are not clinical tools and must not be used to make decisions about anyone's health.
Advertising
The site is funded by advertising served through Google AdSense. Adverts are not endorsements, and we have no control over the specific advertisers shown. See the privacy policy for the data implications and how to opt out.
Changes to these terms
These terms may change; the current version is always the one on this page, and this version is current as of August 2026. Continuing to use the site after a change means you accept the version then published.
The site is operated by ZW Studio LLC. Questions: support@zwstudiollc.com.
