Question
The director of the swimming club runs an experiment by examining the impact of 11
factors on average race times across 6 swimming tournaments (6 experimental runs).
(Choose all that are true)
The full model should be fit as the higher order interactions are likely to matter
and there are sufficient degrees of freedom for it.
The design is a supersaturated design because the number of factors is greater
than the number of runs - 1.
Backwards selection should be used to determine which factors significantly
impact race times as model refinement will be needed.
Forwards selection should be used to determine which factors significantly
impact race times as model refinement will be needed and there are insufficient
degrees of freedom to fit the full model.
