Select a model in the list to see its formula in the Formula box.
Click Show Graph to show a 2-D theoretical curve for one-parameter models and a 3-D surface plot for
two-parameter models. No graph is available for models with more than two explanatory (X) variables. On
the graph window, change the default initial values of parameters using the slider, or clicking and typing
values in directly. See Figure 9.15.
