ORANGE Navigator & Optimizer Frequently Asked Questions
Question number FAQ-0975
Is there a guideline for what percentage of virtual illuminance corresponds to what model evaluation (R2 value)?
→It depends on the characteristics of the response.
A clean response, such as fuel efficiency, results in a higher model rating relative to the level of illumination.
As a rough guideline, a plan of approximately 60% is recommended for the second-order model. The virtual illuminance is set to 50% in a two-level, full-factor design.
