ANCOVA without the coding burden. Statistically governed.

Go from your dataset and research question to a reviewed ANCOVA analysis and professional report — with independent plan review, deterministic computation, and built-in statistical guardrails.

How it works

From research question to analysis report.

r2go separates planning, review, statistical execution, and reporting so the workflow is explicit rather than hidden inside a single prompt.

01

Upload & describe

Provide your dataset and describe the analysis question in ordinary language.

02

Plan & review

A structured ANCOVA plan is created and independently reviewed before execution.

03

Clarify if needed

Missing or ambiguous statistical decisions are surfaced for clarification and revision.

04

Run & validate

The deterministic engine executes the model and applies statistical guardrails and diagnostics.

05

Download your report

Receive a professional Word report with the primary result, adjusted estimates, model-validity assessment, diagnostics, warnings, and interpretation.

Why r2go

AI assistance without handing statistical control to a chatbot.

General-purpose AI can explain ANCOVA or generate code. r2go is designed to govern the analysis workflow itself.

Structured specification

Outcome, groups, covariates, contrasts, confidence level, missing-data handling, and analysis role are explicitly defined.

Independent review

The initial plan is checked by a separate review step before statistical execution.

Deterministic computation

Final ANCOVA calculations are performed by a controlled statistical engine.

Explicit guardrails

Model assumptions and predefined blocking conditions are checked rather than silently ignored.

Current ANCOVA release

Focused scope. Explicit boundaries.

The early-access release is intentionally narrow: it supports governed ANCOVA well and blocks unsupported interaction questions rather than routing them into the wrong model.

Supported now
  • Continuous outcomes
  • Continuous and categorical covariates
  • Two-group and multi-group ANCOVA
  • Adjusted marginal means
  • Pairwise contrasts with Tukey adjustment
  • All-versus-reference contrasts with Dunnett adjustment
  • Explicit single A-vs-B contrasts without multiplicity adjustment
  • Confidence intervals and hypothesis tests
  • Model diagnostics and statistical guardrails
  • Professional Word analysis report
Not in this release

Interaction models

Interaction questions are intentionally kept outside the ANCOVA workflow in the current release.

Why this matters r2go is designed to recognize unsupported analysis requests rather than force them through the wrong statistical model.
Your deliverable

One analysis. One professional report.

Early-access users receive a single default deliverable: a downloadable Word report designed to communicate the analysis clearly without exposing internal system artifacts.

  • Primary result and interpretation
  • Adjusted estimates and contrasts
  • Model validity summary
  • Warnings and caveats
  • Diagnostic figures

FAQ

Before you start.

Does r2go simply ask an AI model to run my statistics?

No. AI assists with planning, review, clarification, and interpretation. The final ANCOVA computation is performed by a controlled deterministic statistical engine.

Do I need to know R?

No. The workflow is designed for users who understand their scientific question but do not want to write analysis code.

What do I receive after the analysis?

The default early-access deliverable is a downloadable Word file named Analysis_Report.docx.

Does the current version support interaction models?

No. Interaction models are outside the current ANCOVA release and are intentionally blocked from being routed into the ANCOVA workflow.

Is r2go a substitute for professional statistical judgment?

r2go is an analysis tool that structures and executes supported workflows. Users remain responsible for study-specific scientific and regulatory decisions.
