Analysis That Gets Approved
Every study or model lives or dies on its statistics — weak methodology can cost you a grant, a publication, or trust in your results.
Keestat brings PhD-level biostatistics expertise to power calculations, trial design, and independent statistical validation, without the delays of academic queues or the risk of unverified AI output.
Rigorous Methods
Established methodology, fully documented for scrutiny.
Independent Validation
Objective review built to withstand peer and funder scrutiny.
Fast Turnaround
Defensible results in days, not weeks.
Proven Results
Statistics that hold up under review, without exception
Our Consulting Process
Our Proven Consulting Process
A clear, structured path from your first question to a result that holds up under review.
Every project moves through the same rigorous process, so you always know what stage you're at and what's coming next.
Discovery & Analysis
We review your protocol, hypotheses, and data to understand exactly what the analysis needs to prove.
Strategy Development
We design the statistical approach — power calculations, endpoints, and methodology — matched to your study's goals.
Implementation
We run the analysis or build the plan, with full documentation of every assumption and method used.
Monitoring & Optimization
We review interim results or draft outputs together, refining the approach if your protocol or data changes.
Evaluation & Reporting
You receive a final, submission-ready deliverable — SAP, power calculation, or report — with clear explanations behind every number.
