Determination of number of habitats in simulated data. (A–C) Representative signal-versus-time curves at varying SNR levels for simulated datasets with one, two, and three signal-versus-time curve patterns, respectively. (D–F) Figures show signal-related PCs and the next highest noise-related PC for simulated datasets with one, two, and three signal-versus-time curve patterns, respectively. The percent total variance is indicated for each PC.
