Conversion formula: Standardised Dispersion Analysis (SDA) estimate of self-affinity parameter (SA) to an informed estimate of the fractal dimension (FD).
sa2fd_sda(sa, ...)Self-afinity parameter estimate based on SDA slope (e.g., fd_sda())).
Other arguments
An informed estimate of the Fractal Dimension, see Hasselman(2013) for details.
Note that for some signals different PSD slope values project to a single SDA slope. That is, SDA cannot distinguish dplyr::between all variaties of power-law scaling in the frequency domain.
