Solve the optimization problem for the sample allocation by numerical optimization in the case of sampling estimator targeting the variance.
Description::
Employ numerical optimization to solve the optimization problem for finding the optimal sample allocation when targeting the variance. This option needs NPSOL (preferred choice) or OPTPP (alternative choice) installed.

Examples::
The following method block

.. code-block::

    method,
     model_pointer = 'HIERARCH'
            multilevel_sampling
       pilot_samples = 20 seed = 1237
       convergence_tolerance = .01
       allocation_target = variance
        optimization


uses the variance as sample allocation target and solves the resulting optimization problem using numerical optimization.
