forming an hypothesis test inversion by scanning
  the hypothesis test results of the <tt>HybridCalculator</tt> for
  various values of the parameter of interest. An upper (or lower) limit  can be derived by looking at the
  confidence level curve of the result as function of the parameter of
  interest,  where it intersects the desired confidence level.</li>
