Open Source

In order to ensure anybody can verify our calculators and generators, we have made the code that performs all calculations on this site open source.

You can view all of the source code for the calculations used on this site at our GitHub organization. Within the organization, we have seperate code repositories for power and sample size calculators, study design generators and subject allocation and randomization functions.

If you have any questions, please contact us. We look forward to hearing from you.
