Which of the following is true of model refinement? (Choose all that are true) Single replicate designs require model refinement as fitting the full model will lead to a lack of degrees of freedom to estimate the Sum of Squares Error. Assuming no replication, fractional factorial designs requir model refinement as fitting the full model will lead to a lack of degrees of freedom to estimate the Sum of Squares Error. Practical significance can be considered when doing model refinement. For replicated full factorial designs, it is necessary to use lenth's pseudo standard error for model refinement when fitting the full model.
