sa2fd_dfaR Documentation

Informed Dimension estimate from DFA slope (H)

Description

Conversion formula: Detrended Fluctuation Analysis (DFA) estimate of the Hurst exponent (a self-affinity parameter sa) to an informed estimate of the (fractal) dimension (FD).

Usage

sa2fd_dfa(sa, ...)

Arguments

sa

Self-Afinity parameter estimate based on DFA slope (e.g., fd_sda())).

...

Other arguments

Details

The DFA slope (H) will be converted to a dimension estimate using:

D_{DFA}\approx 2-(\tanh(\log(3)*sa))

Value

An informed estimate of the Fractal Dimension, see Hasselman(2013) for details.
