    Rationale

    The purpose of the revision is to add statistical tests to the Annex A4 to enable the user to determine if linear or power level dependencies for SEC are statistically significant relative to a level independent SEC. F-tests will be added along with any needed F-value tables, and discussion as to the appropriate number of degrees of freedom to use in the tests will also be added.
