Dear colleagues,
from the discussion on these pages I understood that the AR(1) algorithm is
to be used in conjunction with a high-pass filter. I was wondering whether
the specification of the high-pass filter cutoff period is of relevance for
the correction of serial correlations.
More precisely, our current paradigm requires a rather long cutoff period
of 256s. Does this imply the risk of overestimating serial correlations
(similar to not using a high-pass filter at all)?
Help on this issue would be great.
