Statistical Verification

To provide transparency of ARM calculations on reports, we provide examples that can be replicated by clients in other statistical packages (such as SAS or R) to verify the reported values in ARM.
The below Verification Packages address one or more ARM features. Each link below opens a page describing the theory and calculations performed by ARM. These pages may contain links to the following types of files:
  • ARM Report pdf - the report generated in ARM, with the verified values highlighted.
  • Report sets - the ARM report set used to generate Report.pdf in ARM.
  • SAS file - a SAS script for duplicating the analysis in the SAS program.
  • SAS Report pdf - the report generated from SAS used to verify the ARM report.
