Strange spectral methods find solar signal in alkenes
Via the Club du Soleil, I’ve found another paper using spectral analyses to find a solar signal in palaeoecological data. Working on sediment from Lake Challa, a deep crater lake near Mt. Kilimanjaro in Tanzania that has been used in … Continue reading
From the Appendix of Mann & Lees 1996
The appendix of Mann & Lees (1996) includes this note regarding fitting a AR(1) process to a power spectrum S(f): A fit to S(f) will be more weighted towards the low-frequency, high amplitude portion of the spectrum than a fit … Continue reading
