		<td>Description:</td>
		<td>This model demonstrates the use of the Response Surface Method (RSM) approximation plugin
			to fit a model to data for a cantilever beam.  Fourth order response surfaces are fit using
			the stepwise regression term selection approach.  An optimization of the cantilever beam is
			performed using the resulting approximation model.
			<p><br>
			Load the model and review the approximation model:
			<ul>
				<li>Right click the optimization component and select 'Approximations'
				<li>Click 'View Data' to review data points, error analysis points, and coefficient fit data
				<li>Click 'Error Analysis...' to review goodness of fit for each response
				<li>Click 'Visualize...' to raise the approximation viewer;  adjust sliders, review 2D and
					3D graphs, zoom in on specific graphs for detailed visualization
			</ul>
			Run the model.  Compare optimization results to those obtained without the approximation model
			(run optimization examples or deactivate approximation model and re-run).
