Abstract: cfitzrw filters one or more time series using the Christiano-Fitzgerald Random Walk band-pass filter described in Christiano and Fitzgerald (Int Econ Rev, 2003). They demonstrate that the filter, an approximation to the "ideal" band-pass filter, is reasonable for economic timeseries which are approximately random walk processes. In contrast to the Baxter-King filter (bking), the CF-RW filter is neither symmetric nor time-constant, but is capable of processing the entire time series.
