From: Spectral estimation in unevenly sampled space of periodically expressed microarray time series data
Simulated data. Comparison of spectral estimation for simulated data: (a) simulated cosine signal with even sampling (N = 48), (b) the periodogram of the simulated signal in (a) obtained using the Fourier transform, (c) simulated noisy cosine signal with uneven sampling, (d) the periodogram of the signal in (c) obtained using the Lomb-Scargle method (dashed line), and the periodogram of the signal in (c) obtained using our method (solid line).
