“…The third model, shown in Figure 4c, (Gaiewski, Dunleavy, & Geis, 1994) is used here because it has the same number of elements as the first model but in a different configuration and so should have about the same accuracy as the first model (Gaiewski, Dunleavy, & Geis, 1994). The last model is much more complicated and so should have a longer solution time but much more accurate fit to the data.…”
