Note that four factors have been highlighted. Factors X10, X15, and X7 are active based on a 0.05 critical value criteria. In the Half Normal Plot, X18 is close to the blue line, which indicates that it is close to the 0.1 cutoff value for significance. The 0.1 critical value is generous in its selection of factors so that you do not miss those that are possibly active.
The contrast estimates for X10, X15, and X7 of 5.1, –3, and 1.8 are close to their simulated values (5, –3, 2).
