      A <code>tier 1 model</code> quantifies the Measurement using activity data (i.e.,

      A <code>tier 2 model</code> quantifies the Measurement from activity data using a

    <li>
      A <code>tier 3 model</code> quantifies the Measurement from activity data but uses
      equations or algorithms that differ from the <code>tier 1 model</code> and

      and statistical models with various forms.
