A plot fitting the model f on top of the lizard sample dataset showing the residuals between the data points and the model. The S-value is about 1.59.

A plot fitting the model g on top of the lizard sample dataset showing the residuals between the data points and the model. The S-value is about 5.91.
What do you Notice? What do you Wonder?

1 How is the fit-model plot for cy’s model similar to the fit-model plot for jo’s model?

2 How is the fit-model plot for cy’s model different from the fit-model plot for jo’s model?

3 What do you think the three terms in the legend refer to?

  • Model:
