Statistical Data Analysis
We analyse your study data according to its question and plan, and deliver results tables with a clear explanation of each result.
Data Cleaning and Preparation
We organize your dataset, handle duplicates and missing or inconsistent values, and deliver an analysis-ready copy with a log of every change.
We review variable names, types, coding and units, and flag duplicates and missing or implausible values. No record is removed and no value is changed without a rule you approve, and missing values are never invented.
You receive your original file unchanged, a cleaned copy, a codebook and a log of changes and open queries.

Common questions
When does project work begin?
The estimated delivery period begins after payment is verified and the required non-sensitive materials are received and approved through the agreed communication channel. Each service defines its requirements.
Is publication or manuscript acceptance guaranteed?
No. Publication, acceptance, and assessment decisions belong to the relevant institutions. We do not guarantee publication, grades, or research outcomes.
Can I send research files or patient information here?
This website does not accept research files or patient data. Keep form submissions general and non-sensitive. Any necessary communication process is agreed after review.
How do I track my order?
After you place your order, we email you a link to your private order page. There you can see each stage of the work and its date, what we need from you, and our latest notes, and we email you whenever the stage changes. If you lose the link, open "Track your order" at the bottom of any page and enter your email and order number, and we'll send the link to the email on your order.
