WebHigh-pass (HP) filtering is almost universally done in fMRI studies. fMRI data has a lot of noise at low temporal frequencies (slow drift). This is also a main source of autocorrelation in fMRI time series data. HP filtering models ("captures") and removes low-frequency signals. This can be done in the time domain and in the frequency domain. Web11 jul. 2015 · For instance, if you have daily data and want to filter out a weakly pattern, set period to 7. If you have monthly data and want to filter out a yearly seasonal pattern, set period to 12. If “kind” is “additive”, the decomposition is data = trend + seasonal + irregular.
