Figure 23-4: Reversing F1 and F2 yields another candidate model
This is just one pair of models where reversing the roles of F1 and F2 changes one
member of the pair into the other. There are other such pairs. Models 52 and 53 are
equivalent, although they are counted separately in the list of 4,096 candidate models.
The 10 models in Figure 23-3 on p. 354 come in five pairs, but candidate models do
not always come in equivalent pairs, as Figure 23-5 illustrates. The model in that figure
does not occur among the 10 best models for six optional parameters and is not
identified for that matter, but it does illustrate how reversing F1 and F2 can fail to yield
a different member of the set of 4,096 candidate models.
