 # Plot ROC Curves
-# -----------------------

 #
 # We can also plot the Receiver operating characteristic (ROC) Curves based on forecast and testing-catalog.
-# In the figure below, False Positive Rate is the normalized cumulative forecast rate, after sorting cells in decreasing order of rate.
-# The "True Positive Rate" is the normalized cumulative area. The dashed line is the ROC curve for a uniform forecast,
-# meaning the likelihood for an earthquake to occur at any position is the same. The further the ROC curve of a
-# forecast is to the uniform forecast, the specific the forecast is. When comparing the
-# forecast ROC curve against an catalog, one can evaluate if the forecast is more or less specific
-# (or smooth) at different level or seismic rate.
