A) Time series varying with respect to the strength or persistence of long range correlations. B) Power spectral analysis of the white, pink, and brown noise time series. Long-range correlations indexed by the slope (β) of a regression line filled to the log-log power spectrum. The variation of fluctuations across scales for white, pink, and brown noise is depicted with sine waves. C) Detrended fluctuation analysis of white, pink, and brown noise time series. Long-range correlations indexed by the slope (α) of a regression line filled to the data.
