Five services. A clear starting point.

What do you need to move forward?

Each service answers a different question. If your project spans more than one, we will agree on the combination before work begins.

01 · Methods & reporting

Statistical Manuscript Review

“Are my methods and interpretations appropriate?”

An independent review of your methods, results and tables, with issues located in the manuscript and suggested fixes.

  • Model specification and relevant assumptions
  • Statistical reporting and internal consistency
  • Structured findings and next steps
Tiered scope · Standard: 5 business days
Explore manuscript review
02 · Claim-to-output checking Pilot

Manuscript Results Check

“Does the paper match my analysis output?”

Trace the numbers in agreed manuscript sections to the intended R or Python results. Identify outdated values, mismatched labels and unsupported claims.

  • Up to 80 agreed numeric claims
  • Rounding, sign, unit and denominator checks
  • Claim-by-claim evidence and human review

03 · Code & environment Pilot

Reproducibility Check

“Can someone else rerun this result?”

Rerun one agreed output from your R project and identify the package, dependency or setup problems that get in the way.

  • One target output and environment
  • R session and dependency record
  • Output comparison and prioritized fixes

04 · Reviewer-requested analysis Pilot

Reanalysis Execution Sprint

“Can you run the analyses my reviewers requested?”

Execute a bounded analysis plan on your existing data, independently check the models, and document the changes for your revision.

  • One reviewer letter, up to three analyses
  • Reproducible R code and revised tables
  • Change log and reviewer-to-result crosswalk

05 · Shortened measures

Psychometric Defense Appendix

“What evidence supports the shortened scale we used?”

Assess your abbreviated measure using item-level responses and document the findings, limitations, and implications for your manuscript.

  • Reliability and factor-structure assessment
  • IRT precision and item-dependence checks where appropriate
  • Psychometric appendix and reviewer-response draft

One shared approach

A clear scope before the work starts.

01

Tell us the question

Describe your project, deadline and the help you need. Start with a description; file access and data arrangements come later.

02

Approve the plan and quote

We confirm the service, deliverables, fee and schedule. A sprint also needs your approval of the analysis plan before execution.

03

Get documented work

Receive the agreed review, comparison, rerun record or reanalysis outputs, with human review and any limitations stated.

Examples matched to the service.

Inspect the kind of evidence you can work through, from manuscript findings to source-linked results.

Manuscript Results Check

A claim-to-output record

A synthetic example compares reported values with the intended model and traces each finding to its source.

See the sample results check
Reanalysis Execution Sprint

A reviewer-to-result crosswalk

A synthetic example shows the request, analysis action, original result and revised result.

Post-Submission · Revise & Resubmit

Statistical reviewer comments? Get a clear plan for your revision.

Understand what needs to change, which additional checks are justified, and how to explain your methodological decisions.

The Reviewer Response Audit is a Statistical Manuscript Review focused on your revision. After we agree on scope, share your manuscript, the relevant decision-letter comments and your current response draft, if you have one. Get a point-by-point statistical action plan mapped to the agreed reviewer comments.

  • Reviewer comment assessment — Turn methodological concerns into specific questions, checks and next steps.
  • Assessment of additional analyses and methodological justification — Identify when an additional check is warranted and when an explanation of your existing approach may address the concern, with methodological references where relevant.
  • Response support — Plain-language statistical explanations and suggested points to address in your response. You write the response letter.
  • Revised table and text checks — Check consistency in agreed manuscript and response sections against supplied analysis output. A full claim-by-claim Manuscript Results Check is scoped separately.

Standard turnaround: five business days from complete materials and first payment. One clarification call or email thread is included.

Illustrative example · Not from a client report

Reviewer comment
“Please explain how classroom clustering was handled in the analysis reported in Table 3.”

Assessment · Clustering requires review
Check how classroom clustering was handled in the original model. Assess an appropriate small-sample adjustment or alternative model, identify any necessary sensitivity analysis, and explain the implications for Table 3. The recommendation depends on the study design and available evidence.

Need models rerun or new analyses executed? Request a separately scoped Reanalysis Execution Sprint. We respond to quote requests within 72 hours; execution timing is confirmed in the quote.
