I used the AR modelling written for R (S) on blood pressure and heart rate
signals. I used 60 one second samples and a model order of 20. I used the
"ar" finction in the "ts" package.
Given that blood pressure is measured in mmHg would the spectral density (on
the graph displayed be [mmHg]sq/Hz ?
And the heart rate is measured in Beats Per Minute (bpm) - so would the
displayed spectral density be in (bpm)sq/Hz ?
I'm sorry if this seems a trivial question, however the resultant values
seem inconsistent with published data (although the spectral shape seems
