Has anyone performed spectral analysis of heart-rate variability (HRV) data using SAS? If so, would you mind sharing your syntax with me? It looks like it is possible to do so with PROC SPECTRA or PROC TIMESERIES (although it seems that, for the latter, I would need SAS Forecast Server, which I do not have). If possible, I would love to avoid re-inventing the wheel.

Thank you!
