Frequently Asked Questions

Everything you need to know before you start

Is Dr.AIStat really free?
Yes. Dr.AIStat is 100% free and open-source under the MIT license, with no subscription, paywall, or usage limit. R, RStudio, and the AI interpretation (via Groq's free API) are all free as well.
Do I need to know how to code in R?
No. You run three one-line commands once to install it, then Dr.AIStat opens as a point-and-click app in your browser. You upload an Excel or CSV file and choose analyses from menus — no scripting required.
What kinds of analysis can Dr.AIStat run?
15 modules: descriptive statistics, measurement (EFA/CFA, reliability, validity), group tests (t-test/ANOVA), regression, machine-learning classification, clustering, IRT, endogeneity, SEM and PLS-SEM, mediation/moderation (CoMe), bibliometrics, fsQCA, and STATA-style methods such as panel, survival, and ARIMA/VAR.
Is my data private?
Yes. All analyses run locally on your own computer and your dataset is never uploaded to any server. Only the short text summary of results you choose to interpret is sent to the AI service.
Can Dr.AIStat replace SPSS, AMOS or SmartPLS?
For most research workflows, yes. Dr.AIStat covers CB-SEM and PLS-SEM, CFA, mediation and moderation, and the assumption checks you would run in SPSS, AMOS, or SmartPLS — and it adds free AI interpretation and APA-ready output.
How is the AI interpretation free?
It uses Groq's free API with the llama-3.1-8b-instant model. You create a free API key at console.groq.com/keys and paste it into the sidebar. No credit card is required.
