%description
Decomposition of time series into trend, seasonal, and remainder
components with methods for detecting and characterizing abrupt changes
within the trend and seasonal components. 'BFAST' can be used to analyze
different types of satellite image time series and can be applied to other
disciplines dealing with seasonal or non-seasonal time series, such as
hydrology, climatology, and econometrics. The algorithm can be extended to
label detected changes with information on the parameters of the fitted
piecewise linear models. 'BFAST' monitoring functionality is described in
Verbesselt et al. (2010) <doi:10.1016/j.rse.2009.08.014>. 'BFAST monitor'
provides functionality to detect disturbance in near real-time based on
'BFAST'- type models, and is described in Verbesselt et al. (2012)
<doi:10.1016/j.rse.2012.02.022>. 'BFAST Lite' approach is a flexible
approach that handles missing data without interpolation, and will be
described in an upcoming paper. Furthermore, different models can now be
used to fit the time series data and detect structural changes (breaks).
