Flag Toggled to Larger Size The flag shows the predicted response at that point on the plot, plus: • Lower 95% confidence bound of prediction • Upper 95% confidence bound of prediction • Standard error of the mean • Standard error of one prediction • Exact composition at the flag location You can plant as many flags as you want. Go ahead, have some fun! Don’t bother doing it now, but you can print the contour plot (or other model graphs) by selecting File, Print. 3D plot of the Response Surface To look at the surface in three dimensions, select View, 3D Surface. 3D Mixture Plot 7-20 • Mixture Design Tutorials Design-Expert 6 User’s Guide
Standard Error Plot Rev. 5/10/02 Now try rotating the plot for a different perspective. Just use the hand to drag the rim of each wheel. Watch the 3D surface change. It’s fun! See if you can get a better viewing angle. Control for Rotating 3D Response Plot Press the Default button when you’re done playing. The graph then re-sets to its original position. Notice that you can also specify the horizontal (“h”) and vertical (“v”) coordinates. It is now time to leave the contour plots and examine the standard error plot. The standard error plot shows how the variance associated with prediction changes over your design space. Select View, Standard E rror and 3D Surface to generate the graph. In order to get a realistic view of the graph, let’s change the z-axis scale. Right click somewhere on the graph and select the Graph Preferences option. Change the Z axis scale (default choice) to these settings: Low of 2, High of 10, Ticks of 5 (the default). Then click on OK and the graph should look like the one shown below.
