+structural changes in (linear) regression models.  It features tests/methods
+from the generalized fluctuation test framework as well as from the F
+test (Chow test) framework.  This includes methods to fit, plot and test
+fluctuation processes (e.g., CUSUM, MOSUM, recursive/moving estimates) and F
+statistics, respectively.  It is possible to monitor incoming data online
+using fluctuation processes.  Finally, the breakpoints in regression models
+with structural changes can be estimated together with confidence intervals.
+Emphasis is always given to methods for visualizing the data.")
