Apply yearly high/low-pass filter
This option filters all Januaries, all Februaries with a high-pass or
low-pass filter. Adjacent months (days, pentads, decades) do not
influence each other. This option is rarely needed: almost all
analysis forms have the option to apply high- and low-pass filters as
with f the filtering function. In case of an even number of
years the result is centered on yr-1/2.
Note that this filter does not preserve causality, unlike the
filters that are present on the correlation pages.
The dataset that results from his operation will be available for
three days under View, upload your time series or View,
upload your field in the menu on the right.
At the moment only a running-mean filter is available. More
filters are planned, contact me if you need one (or
better, have one that you'd like added).
