Figure 2.

Examples of stimulated data and estimated segments. Two sets of randomly simulated data (chosen from the 50th random grid formation and the 50th iteration of that formation), one for each simulation run (using the intermediate r level, 2 for simulation 1 and 1.75 for simulation 2), are illustrated as an example with estimated segments from competing models. Segments are represented using the estimated segment averages. The true underlying grid used for data simulation is shown as the solid line in beige.
