Question number FAQ-0975

Is there a guideline for what percentage of virtual illuminance values corresponds to what level of model evaluation (R2 value)?

→It depends on the characteristics of the response.
Clean responses like fuel efficiency tend to have higher model evaluations relative to illuminance.
As a rough guideline, a 60% plan is generally recommended for second-order models. Note that the virtual illuminance is set to be 50% in a two-level full factorial design.
