  1. a CV (%): coefficient of variance, is the standard deviation which is expressed as a percentage of the mean.
  2. b R2: is the measure of variation around the mean explained by the model.
  3. c Adjusted R2: is the measure of variation around the mean explained by the model, adjusted for the number of terms in the model. The adjusted R2 decreases as the number of terms in the model increases provided those additional terms do not add value to the model.
  4. d Adequate precision: compares the range of predicted value at the design points to the average prediction error.
