In the Evaluate Design report, the Fraction of Design Space Plot shows relative prediction variance as a function of the proportion of the design space. It is desirable to have a large proportion of the design space with low prediction variance values. Red dotted crosshairs mark the value that bounds the relative prediction variance for 50% of design space.

Note: Random sampling of the design space is used in constructing the Fraction of Design Space Plot. Therefore, repeated plots for the same design might vary slightly.
