Visualisation of the relationship between Statistical Information and ROC curves.

The left graph shows curves on a cost-loss plot.

The right graph shows the same curves converted to an ROC representation with prior probability for the positive class controlled by π.

Move your mouse over the cost space window to see the corresponding line in the
ROC graph and *vice versa*.

The prior π can be modified using the slider underneath the graphs.

The duality relationships are computed using the geovex Java library while the visualisation is done with the standard Processing library and the geomerative library.
