Figure 2: The effect on the evolution of the particles when changing one parameter of the model. Each particle represents a possible value of the quantity of interest and the latent variable as point in the 2-dimensional plane. The particles move according to the dynamics of the model through this plane. Changing the parameters affects the dynamics of the particles, making spikes or excursions less likely. Though visually pleasing, this prototype does not produce very satisfactory results, a prominent limitation is that the applet in which the visualisation is generated only gives access to very crude forms of "randomness".
