Verify the Calculation: An Example
The calculation requires Independent Verification. The calculation includes the coding, the data provided to the code at run time, built in options chosen by the user at run time, and the qualifications of the user.
An excellent piece of Independent Verification accomplished without the benefit of source coding, and actually without any publicly available equations whatsoever. Exactly why the equations and codes are kept secret from the people who paid for them is another very significant issue. Keeping models, methods, procedures, and associated source code secret is not a part of the accepted scientific method.
