%description
A fast implementation with additional experimental features for testing,
monitoring and dating structural changes in (linear) regression models.
'strucchangeRcpp' 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.
cumulative/moving sum, recursive/moving estimates) and F statistics,
respectively. These methods are described in Zeileis et al. (2002)
<doi:10.18637/jss.v007.i02>. Finally, the breakpoints in regression models
with structural changes can be estimated together with confidence
intervals, and their magnitude as well as the model fit can be evaluated
using a variety of statistical measures.
