Statistical consulting services

Statistical support for critical quantitative decisions

Choose a focused methodological service or a connected project from design through reporting. Start with the decision, not a software procedure.

Problem-led support

Choose the decision that needs support

Each service explains when it is useful, the questions it can answer, and the possible handover.

01

Quantitative Methodology & Analysis Planning

Align research questions, constructs, variables, design, and analysis before the workflow becomes expensive to change.

Best when: At proposal, protocol, or pre-analysis stage when the study logic is not yet explicit.

Questions it can answer

  • What is the estimand?
  • Do the variables answer the question?
  • Which assumptions need contingencies?

Possible handover

Statistical Analysis Plan / Decision table / Pre-analysis checklist

02

Power Analysis & Sample Size

Build a sample-size rationale around the actual design, estimand, uncertainty, clustering, attrition, and feasible recruitment.

Best when: Before collection, during protocol revision, or when a design change invalidates an earlier calculation.

Questions it can answer

  • Which effect-size input is defensible?
  • How do clustering or repeated measures change power?
  • What does sensitivity analysis show?

Possible handover

Power rationale / Assumption record / Sensitivity summary

03

Data Preparation & Results Analysis

Move from collected data to a documented analysis sequence, diagnostics, sensitivity checks, interpretable results, and clear reporting.

Best when: When data are collected but coding, missingness, model choice, diagnostics, or reporting remain unresolved.

Questions it can answer

  • Is the dataset analysis-ready?
  • Which model matches the outcome and dependence structure?
  • How should uncertainty be reported?

Possible handover

Cleaning log / Analysis code / Tables, figures, and interpretation memo

04

Measurement, Reliability & Validity

Check whether items and scales support the inferences that later models are expected to carry.

Best when: When a survey, instrument, latent construct, or score needs scrutiny before outcome modeling.

Questions it can answer

  • Does the measure behave as intended?
  • Is factor analysis warranted?
  • Is the same construct measured across groups?

Possible handover

Measurement decision log / Factor-analysis summary / Validity limitations

05

Advanced Statistical Modeling

Represent clustered, repeated, censored, latent, nonlinear, missing, or predictive structures without forcing them into a simpler model.

Best when: When ordinary regression cannot represent the design or the decision requires stronger validation.

Questions it can answer

  • What dependence structure matters?
  • How should missingness or censoring be handled?
  • What validation matches the intended use?

Possible handover

Model specification / Diagnostic record / Validation and interpretation summary

06

Statistical Analysis Audit & Second Opinion

Independently review a plan, dataset, script, output, draft result, or AI-assisted workflow before relying on it.

Best when: When an advisor, reviewer, stakeholder, or your own quality check raises doubts about the analysis.

Questions it can answer

  • Does the model answer the stated question?
  • Are assumptions and missingness handled?
  • Can the result be reproduced and interpreted safely?

Possible handover

Priority findings / Revised decision path / Limitations and action memo

07

Reproducible Analysis & Reporting

Turn analytical decisions into traceable code, documented inputs, stable outputs, and a handover another researcher can follow.

Best when: When work must be reviewed, rerun, updated, transferred, or defended after the original analysis.

Questions it can answer

  • Can another person reproduce the result?
  • Are transformations and exclusions documented?
  • Do tables match the final code?

Possible handover

Documented code / Reproducibility checklist / Versioned handover package

08

Research Team Support

Add scoped quantitative capacity for a specialist method, workload peak, independent review, or a consistent multi-study workflow.

Best when: When a lab, institution, nonprofit, or corporate research team needs flexible statistical depth.

Questions it can answer

  • Where is the current capability gap?
  • Which decisions need independent review?
  • How should knowledge be handed back?

Possible handover

Scoped workstream / Review notes / Reusable workflow documentation

A useful first message

Describe the decision, not just the software

Tell us what you are trying to learn, the design and evidence you have, and where uncertainty remains.
