- Least-squares spectral analysis (LSSA) is a method of estimating a frequency spectrum, based on a least squares fit of sinusoids to data samples, similar to Fourier analysis.[1][2] Fourier analysis, the most used spectral method in science, generally boosts long-periodic noise in long gapped records; LSSA mitigates such problems.[3]
LSSA is also known as the Vaníček method[4] after Petr Vaníček, and as the Lomb method[3] (or the Lomb periodogram[5]) and the Lomb–Scargle method[6] (or Lomb–Scargle periodogram[2][7]), based on the contributions of Nicholas R. Lomb[8] and, independently, Jeffrey D. Scargle.[9] Closely related methods have been developed by Michael Korenberg and by Scott Chen and David Donoho.
