Good primer on signal processing.

Thanks. I found an R package which does cosinor analysis on circadian rhythm data here - Chronomics Analysis Toolit. I'll let them do the signal analysis for me. At least I learned enough basics to interpret the results. Big Grin

So what I ended up doing was comparing the coherence of the power spectrum periodograms of each person's actimetry.

I got some longitudinal data collected from an accelerometer ...

I struggled my way up to there...then I sat in a corner and wept. Sadcryface

Yes, make sure you understand the data that you're looking at and that it makes sense with the raw inputs or you're in dangerous waters. Garbage in = Garbage out.
