Extract EDA complexity features

Computes dependency-light EDA complexity descriptors, including sample entropy and detrended fluctuation analysis alpha.

Usage

extract_gazepoint_eda_complexity(
  dat,
  eda_col = "GSR_US",
  group_cols = NULL,
  min_samples = 32,
  sampen_m = 2,
  sampen_r_multiplier = 0.2
)

Arguments

dat

A data frame containing EDA data.

eda_col

EDA/conductance column.

group_cols

Optional grouping columns.

min_samples

Minimum finite samples per group.

sampen_m

Embedding dimension for sample entropy.

sampen_r_multiplier

Tolerance multiplier applied to within-group SD.

Value

A list with overview, features, and settings.
