Source: R/dsp_waveform.R
morie_dsp_ruler_fd.Rd

Slope-based estimator from polygonal lengths at log-spaced ruler sizes. Equivalent up to sign convention to Higuchi.

Usage

morie_dsp_ruler_fd(x, n_rulers = 10L)

Arguments

x

Numeric vector.

n_rulers

Number of ruler sizes. Default 10.

Value

Scalar fractal dimension.
